How to build a bottom-up market estimate for AI document processing
AI document processing: Build a bottom-up market estimate from a defined buyer population and a plausible purchasing unit.
Build a bottom-up market estimate from a defined buyer population and a plausible purchasing unit. Start with the segment the company could actually serve. Separate reachable accounts from an entire industry's headline spending.
Start with the decision
Show the count source, inclusion rules, annual spending assumption, adoption constraints, and sensitivity to each input. Use ranges where evidence is weak. Keep the initial obtainable segment distinct from an expansion thesis.
The illustrative scenario
This is an educational workbook. The company or fund and all numerical inputs below are fictional. They are not ADIN results, customer claims, market benchmarks, or a forecast.
The fictional product extracts invoice data for an accounts payable team. Staff review exceptions before information enters the accounting system. Supplier formats and duplicate documents make the input stream uneven.
A misplaced decimal or duplicate record can matter more than an average extraction score. Define the fields and events that require review before comparing workflows.
Separate a market assumption from its arithmetic
Assume the fictional team has $220,000.00 available and uses $34,000.00 each month. Dividing gives 6.5 months under a constant-burn assumption. That quotient ignores payment timing, hiring, one-time bills, and uncertain collections. It is a starting point for a dated cash plan, not a prediction of when the company will run out of money.
The market side of the same exercise assumes 1800 reachable accounts, each spending $25,200.00 annually. Multiplication explains the model; it does not establish that those accounts exist, can be reached, or will pay. Replace each invented input with sourced evidence and preserve a smaller-segment scenario.
Connect the two models only after identifying the customer milestone the budget can support. Compare correct, reconciled records with the current process. Include document intake, exception review, and corrections after export in the time and cost model. A financing plan should show the work and decision dates between current evidence and that milestone. Keep future financing and market expansion conditional, and ask a qualified finance professional to review formal forecasts.
| Item | Illustration |
|---|---|
| Fictional cash available | $220,000.00 |
| Assumed monthly net cash use | $34,000.00 |
| Simple runway quotient | 6.5 months |
| Assumed annual customer spending | $25,200.00 |
| Illustrative reachable accounts | 1800 |
| Account count × annual spending | $45,360,000.00 |
Use this worksheet
Answer the questions with a source, date, owner, and next action. Mark an unknown as unknown. Use public or permissioned information and involve a qualified specialist when a question requires expertise beyond the team’s competence.
- Who is counted?
- Why are they eligible buyers?
- What annual unit is assumed?
- Which source supports the count?
- What constraint limits reach?
Questions specific to this scenario
- Which fields require exact agreement?
- How are duplicate invoices handled?
- Who signs off on reconciliation?
Use permissioned documents, field-level corrections, duplicate flags, and reconciliation results. Keep document type and supplier format visible instead of relying on one blended score.
A concrete next test
Select permissioned invoices from different supplier formats and include a duplicate. Trace each field through correction and export to reconciliation. Ask the accounts payable owner which error would block use even if most fields were extracted correctly.
Interpret the result
The estimate is useful when a reader can replace an assumption and understand the result. Arithmetic does not validate a buyer count or willingness to pay; those inputs need separate evidence.
Compare correct, reconciled records with the current process. Include document intake, exception review, and corrections after export in the time and cost model.
