02 / CHOOSE AN APPROACH

## Start with the setup your work needs.

Tool categories overlap. These four starting points help you decide which questions to bring to the comparison.

### Extract, review, export

You need selected fields and line items in a spreadsheet, import file or configured system handoff.

Can the team use the output without retyping it?

[Explore DigiParser workflows](/solutions/for-manufacturing)

### Rules and templates

Recurring layouts make an explicit parsing setup useful. Include the effort of maintaining variations.

What changes when a sender changes the layout?

[Explore a rules comparison](/compare/docparser)

### Email-based intake

The workflow starts in an inbox. Compare email bodies, attachments and the organization of incoming streams.

Does the setup handle all the formats you receive?

[Explore an intake comparison](/compare/parseur)

### Workflow and validation

You need checks or processing steps around the document, with a clear route for exceptions.

Which controls are configured, and who owns them?

03 / YOUR WORKFLOW

## Compare for the job your team actually does.

A customer PO and a supplier invoice belong to different business processes. Choose the right sample, owner and output for each.

CUSTOMER -> YOUR TEAM

### Customer purchase orders

Support order entry or order tracking. Start with the information needed to accept and process an incoming customer order.

Who to involve

The person handling incoming orders, customer service or the office workflow.

What to test

Product references, quantities, units, requested dates and every line across pages.

Useful output

An Excel tracker, import file or configured order-system handoff.

[Explore customer PO extraction](/solutions/purchase-order-parser)

SUPPLIER -> YOUR TEAM

### Supplier invoices

Support AP review and entry. Start with the fields your team needs to review a supplier bill and prepare the accounting data.

Who to involve

The person handling AP, accounting or combined office and accounts work.

What to test

Supplier reference, dates, currency, line items, tax, invoice total and balance.

Useful output

A spreadsheet, import file or configured accounting-system handoff.

04 / MAKE THE COMPARISON USEFUL

## Test the same work. Compare the whole result.

Pick two or three tools. Use the same representative files and the person who will use the result. These five checks make the decision more useful than a feature count.

01

### Your real document mix

Include digital files, scans, long tables, changing layouts and repeat documents.

02

### The fields that matter

Count missing rows and incorrect quantities. A readable PDF is not proof of a usable result.

03

### Review and correction effort

Record the time needed to check and correct a result, including difficult documents.

04

### The actual destination

Confirm identifiers, mappings, duplicate handling and retries for the intended handoff.

05

### Complete cost and setup

Count document length, processing steps, team needs, add-ons and external integration costs.

### Bring a worksheet  
to your evaluation.

Record field accuracy, missing lines, setup time, review time and destination checks for the same samples.

**Running a small office?**

One person may own intake, review and approval. Include that person in the test before planning a larger rollout.

05 / BEFORE YOU CHOOSE

## A few questions worth answering.

Choose by the result your workflow needs, then confirm the details with your samples.

Where should I start if I am comparing document extraction tools?+

Start with DigiParser and the documents your team needs to process. Define the fields and repeating rows, review the result and test the actual export or configured handoff. Use the comparison for your current tool to see the switching case and the scope to preserve.

What is the difference between a comparison and an alternatives guide?+

A comparison helps you choose between DigiParser and one named tool. An alternatives guide gives you a wider shortlist and explains which approach fits different requirements. Use the shortlist first if you are still deciding what kind of setup you need.

Can the same tool handle customer purchase orders and supplier invoices?+

A tool can extract both, but keep the workflows separate. Customer POs support your order-entry or tracking process. Supplier invoices support AP review and accounting entry. Test the fields, responsible person and destination for each.

Does an integration logo mean the tool can write to my ERP?+

Check the specific destination record, field mapping and connection method. A spreadsheet export, automation-platform connection and native ERP write are different routes. Confirm identifiers, duplicates, retries and review controls in your evaluation.

YOUR DOCUMENTS ARE THE BEST NEXT STEP
