Excel is where every growing company starts. But every order, stock movement and invoice depends on someone opening a file. Piston turns those files into one system, run by agents.
Every workflow you built in Excel, Piston runs for you.
The difference is who does the work. In Excel, your team types, checks, and chases. On Piston, agents run the workflow and your team reviews the result.
Trigger a purchase reorder
Agent detects low stock from consumption trends, drafts the PO, and alerts the buyer
Open the stock file, spot the red cell, check quantities against the supplier file, then type the order in an email or a Word template
Launch a production order
Agent creates and schedules the production order from the demand signal. No file to open
Check the orders file, copy quantities into the planning sheet, print it for the workshop, update statuses by hand
Follow up an overdue invoice
Agent sends a context-aware follow-up automatically based on payment terms
Open the AR file, filter the overdue rows, dig up the last email thread, write the reminder and update the tracking column
Answer "What's my margin?"
Ask Piston in plain language. Answer in seconds, no report building required
Export the latest data, rebuild the pivot table, hope the formulas still hold, get the answer by tomorrow
The difference isn't AI. It's who does the work.
Excel has formulas and macros. They calculate, but they don't act. Piston has agents: software that understands context, connects your data, and executes on your behalf.
Acts, doesn't suggest
Piston agents do not generate a to-do list. They execute the workflow: drafting the PO, sending the follow-up, adjusting the schedule. You review the result, not the process.
Speaks your language
Ask Piston anything the way you'd ask a colleague. "What's my overdue AR?" "Which supplier is causing delays?" No report to build, no filter to configure.
Connects across modules
When a production order slips, the procurement agent updates the delivery forecast. The sales agent alerts the customer. Nothing falls through the cracks between departments.

Running on Excel today? We import your spreadsheets and go live in 4 weeks. Your team starts on day one.
Full ERP coverage. No spreadsheets required.
With enough discipline, Excel can track some of this. Most of it, it can't. The column on the right shows what changes when your operations run on a real ERP with agents in the loop.
Available — agent-validated
Agent cross-checks BOM consistency against live supplier data and open production orders, surfacing discrepancies before production starts.
Manual spreadsheet
BOMs live in workbooks that only one person understands. Versions drift, formulas break, and nothing warns you when a component changes.
Agent creates and adjusts in real time
Agent reads demand signals continuously and reschedules production without a planner intervening — no routing templates to maintain.
Manual planning board
Scheduling happens in a weekly spreadsheet ritual. When demand shifts mid-week, the plan is already stale.
Available — agent-monitored
Agent tracks work order progression and flags delays before they cascade — operators stay focused on the work, not on system updates.
Not available
No work orders in Excel. Instructions travel by printout, WhatsApp, or memory, with no status anyone can check.
Native — zero setup
Plants and sites are first-class objects in Piston. No multi-company workaround or partner engagement required.
Separate files per site
Each site keeps its own workbook. Consolidating means emailing files around and reconciling by hand.
Constraint-based, agent-driven
Agent models all work-center constraints and automatically rebalances the schedule when demand spikes or a machine goes down.
Manual estimates
Capacity is a gut call backed by a formula someone built years ago. No live link to actual orders or machine load.
Agent adjusts lead times dynamically
Agent tracks actual vs. expected lead times per supplier and route, and continuously updates planning parameters without human intervention.
Static values
Lead times are typed in once and rarely updated. When a supplier slips, the plan doesn't know.
Available — agent-monitored
Agent monitors subcontractor deadlines and triggers follow-ups or escalations when delays threaten the production schedule.
Tracked by email
Subcontracted work lives in inboxes and a tracking tab. Materials sent, dates promised, quantities returned: all manual.
Agent escalates abnormal rates
Agent compares scrap rates against historical baseline and automatically opens an NCR when deviation exceeds threshold — no operator prompt needed.
Rarely tracked
Scrap gets noted on paper, if at all. Costs never make it back into your margins.
Agent drafts from demand signal
Agent detects a restocking need and drafts a PO before anyone thinks to ask — team approves rather than creates.
Word templates + email
POs are typed by hand from a template, sent by email, and tracked in a spreadsheet nobody trusts.
Agent scores and selects automatically
Agent evaluates vendors on real delivery and pricing history per order line, and selects the best option automatically at time of PO.
Contact list
Supplier info sits in a contacts tab. Prices, lead times, and performance history live in people's heads.
Automatic — no configuration needed
Runs without setup. Agent flags any mismatch immediately and routes the exception to the right person.
Manual, line by line
Someone compares the PO, delivery note, and invoice by hand. Errors slip through, and it eats days each month.
Agent handles end to end
Agent sends RFQs, chases non-responders, collects quotes, and presents a ranked recommendation — one click to confirm.
Email threads
Quotes are requested by email and compared in an ad-hoc table. No history of who quoted what and when.
Agent tracks and alerts proactively
Agent monitors contract utilization and alerts the buyer before commitment windows expire or volumes are exceeded.
Not available
No structured way to track blanket orders. Call-offs against a contract are followed manually, when they are followed at all.
Agent flags at time of receipt
Agent catches quantity and quality discrepancies on receipt in real time, and opens a claim before the shipment leaves the dock.
Found at inventory time
Short deliveries surface weeks later, during a count or a production halt. Too late to claim.
Available — context-aware
Same approval coverage, but agent includes relevant context — supplier history, budget status — so approvers decide faster.
Verbal or email
Approvals happen in the hallway or by reply-all. No trail, no thresholds, no consistency.
Queryable in plain language
Ask "What did we spend with supplier X last quarter?" and get an instant answer — no report building required.
Manual pivot tables
Spend analysis means exporting, cleaning, and pivoting for a day. By the time it's done, it's outdated.
Available
Same coverage. Stock visibility is accessible to all Piston agents and queryable in natural language.
One file per site
Stock levels per site live in separate workbooks. A consolidated view means manual copy-paste.
Available — queryable
Same traceability depth. Agent can answer "Where is lot #441 right now?" or "Which deliveries used this supplier batch?" instantly.
Manual log, if any
Lot numbers get typed into a tab. One typo and the trace breaks. A recall means days in spreadsheets.
Agent-driven, consumption-aware
Agent monitors actual consumption trends and adjusts reorder points dynamically — no static rule to maintain.
Not available
Reordering depends on someone noticing a cell turned red. Stockouts happen when they're on holiday.
Available — agent-suggested
Same capability. Agent can also suggest putaway optimizations based on pick frequency and space utilization.
Not available
Storage locations are tribal knowledge. New warehouse staff learn by asking.
Built-in, agent-enforced
Agent enforces FEFO compliance on every pick and flags lots approaching expiry before they become waste.
Manual dates column
Expiry dates sit in a column, sorted by hand. FEFO depends on discipline, not on the system.
Available
Same capability, fully supported across all agent workflows and cross-module operations.
Formula-based
Conversions live in formulas that break when someone inserts a row. Errors surface as stock discrepancies.
Available
Same costing coverage. Agent can answer margin and valuation questions in plain language without a custom report.
Manual calculation
Valuation is a quarter-end exercise with assumptions baked into formulas. Finance and ops rarely agree on the number.
Agent schedules based on risk
Agent prioritizes high-velocity or discrepancy-prone locations and schedules cycle counts proactively — no planner required.
Full counts only
No cycle counting program. Stock accuracy resets once a year, with a full count that stops the warehouse.
Agent-triggered at every milestone
Inspections fire automatically at configured checkpoints. Agent escalates failed inspections without needing a manual trigger.
Paper checklists
Inspections happen on paper or in a shared sheet. Results are hard to find when a customer asks for them.
Agent opens and routes automatically
Agent detects abnormal results — scrap rate, inspection fail, delivery complaint — and creates the NCR before anyone files it.
Ad-hoc
A non-conformance gets an email and maybe a row in a sheet. No numbering, no follow-up, no closure tracking.
Structured and agent-tracked
CAPA actions are tracked with deadlines and owners. Agent follows up on overdue actions and surfaces recurring patterns.
Not available
Corrective actions are meeting notes. Nothing tracks whether the fix actually happened.
Agent tracks trends and alerts
Agent builds a continuous quality scorecard per supplier and surfaces deteriorating trends before they become systemic problems.
Not tracked
Supplier defects are remembered, not measured. No data to back a tough conversation with a supplier.
Auto-generated on shipment
Piston generates CoC documents automatically at shipment, linked to the relevant inspection records and lot data.
Manual documents
CoCs are Word documents assembled by hand from several files. Slow and error-prone.
Available — queryable in plain language
Same depth, but you can ask "Who approved this production order and when?" instead of searching through log tables.
None
Excel keeps no history of who changed what. An audit means reconstructing events from emails.
Agent manages plan execution
Control plans are configured once. Agent manages execution, tracks compliance rate, and flags when a check is overdue.
Static documents
Control plans are documents disconnected from daily production. Nobody checks them at the line.
Available
Same invoicing coverage. Agent can draft and send invoices triggered by delivery or contract milestone without manual action.
Word/Excel templates
Invoices are built by hand from templates. Numbering errors and missed invoices are routine.
Available
Same coverage. Agents handle multi-currency transactions natively across all procurement and sales workflows.
Manual rates
Exchange rates are typed in manually and updated when someone remembers.
Agent-driven, context-aware
Agent sends follow-ups and adapts the tone to customer history — first reminder is polite, third is firm. No human needed to chase.
Manual chasing
Overdue invoices get chased when someone runs the aging file. Cash sits uncollected in the meantime.
Live — queryable in plain language
Ask "Are we over budget on the Paris project?" and get an instant answer with breakdown — no report to build.
Annual spreadsheet
The budget is a file built once a year. Actuals versus budget is a manual exercise every month.
Agent calculates on demand
Agent can answer "What is the margin on order #442?" or "Which product family is dragging our Q2 margin?" immediately.
Rough estimates
Product costs rely on outdated assumptions. Real margin per product is anyone's guess.
Live + queryable
Standard reports available. Any ad-hoc financial question — "What's our cash position if all open invoices pay on time?" — answered instantly.
Manual monthly close
Reporting means exporting from the accounting tool and rebuilding the same file every month.
Available — agent handles exceptions
Same automation. Agent routes unmatched transactions to the right person with context instead of leaving them in a queue.
Line by line
Bank statements are matched by hand against a payments tab.
Available
Same multi-entity coverage. Intercompany transactions are natively supported across all agent workflows.
Separate files
Each entity has its own set of files. A group view costs you consolidation weekends.
Available — agent-monitored
Agent flags at-risk orders — delivery delays, stock shortages, credit holds — before the customer calls to ask.
Order tracking tab
Orders live in a shared sheet. The status is whatever the last person typed.
Agent drafts from specifications
Rep describes the deal verbally or pastes specs — agent builds the structured quote in seconds with the right pricelist and margins.
Copy-paste from old quotes
Quotes start from the last similar quote. Prices are often outdated, and follow-up depends on memory.
Agent-driven, continuously updated
Agent learns from actual sales patterns and updates forecasts automatically — no model to recalibrate or planner to manage.
Gut feel + last year
Forecasting is last year's numbers plus intuition. No link to the actual pipeline or seasonality.
Available — agent-applied
Same pricelist coverage. Agent applies the correct pricelist automatically at quoting and flags margin exceptions before confirmation.
Multiple versions
Price lists exist in several versions. Each rep quotes from the one on their desktop.
Available
Same portal capability. Customers can also ask questions in natural language about their orders.
Not available
Customers email to ask about their order status, and someone checks the sheet.
Agent handles end to end
Agent opens the RMA from a complaint, coordinates return receipt, triggers quality inspection if needed, and issues the credit note.
Ad-hoc
Returns are handled case by case over email. No process, no data on why products come back.
Available — agent-assisted
Same pipeline visibility. Agent briefs reps before calls with account history and surfaces deals going cold without being asked.
Manual reports
Performance reviews depend on someone building the numbers. Per-rep or per-product views take days.
Available
Same mobile coverage. Piston's conversational interface also works fully on mobile.
Not available
Excel on a phone doesn't work in the field. Reps call the office to get answers.
Available
Same visibility. Rep can ask "How much of product X do we have available for next Tuesday?" and get a confirmed answer.
Call the warehouse
Reps promise stock they can't see. The warehouse confirms after the customer meeting.
Agent-assisted on the spot
Rep describes the deal in plain language; agent builds the structured quote with correct pricing, margin check, and stock availability.
Back-office only
Quotes wait until the rep is back at a desk. Days pass between the visit and the offer.
Agent suggests optimal routes
Agent clusters visits by geography and priority, and suggests the optimal sequence each morning — reps just follow the plan.
Manual
Visit routes are planned in the rep's head or on a printed list.
Agent transcribes from voice
Rep speaks their notes after a meeting; agent structures them, updates the CRM record, and schedules follow-ups automatically.
Rarely done
Visit notes end up in notebooks, if anywhere. Nothing feeds back to the office.
Agent surfaces at-risk deals
Agent identifies behavioral signals — no response, pricing pushback, slipping close date — and flags the deal before the rep asks.
Not tracked
Lost deals and competitor prices are stories, not data.
Ask Piston — any question
"What's my margin on order #442?" — "Which supplier caused the most delays last quarter?" — answered in seconds, no setup needed.
Not available
You can't ask a spreadsheet a question. Finding an answer means knowing which file, which tab, which filter.
Across all 8 modules
Piston agents draft POs, schedule production, chase invoices, route NCRs, and brief sales reps — your team reviews decisions, not paperwork.
Not available
Excel executes nothing. Every action is a human opening a file.
Native cross-module intelligence
Production delay → procurement alert → customer promise updated → sales rep notified. Piston connects all of these without a workflow builder.
Not available
Files don't talk to each other. Connecting sales to stock to purchasing is someone's full-time job.
Agent reasons about risk
Agent monitors trends and surfaces anomalies — rising scrap rate, supplier on-time delivery dropping, margin eroding on a key account — without a rule.
Conditional formatting
A red cell only warns the person who opens the file. Nothing pings the team when something needs attention.
Configure via conversation
Tell Piston what you need in plain language — "Flag all POs over €50k for CFO approval" — and it configures the rule.
DIY formulas
Every workflow is hand-built formulas and macros that only their author can maintain.
Agent manages connections
Describe the integration need — agent handles mapping, error handling, and monitoring of the connection without a developer.
Manual exports
Data moves in and out by CSV export and copy-paste.
Live in weeks — no partner needed
Agents replace the training curve. Your team describes what they need to do, Piston handles the rest. Go-live in weeks, not months.
Instant, then unmanageable
Excel starts free and instant. Three years later, the business runs on 40 linked files nobody dares to touch. Piston goes live in 4 weeks, with your spreadsheets imported.
