01Overview
Define the first accounting workflow to release
Our accounting software development services begin with one finance workflow and a sample of the records it must produce. For bookkeeping automation, we map how data enters your accounting ledger, who approves changes and what a reconciled result looks like.
- CaptureA source document becomes a structured record that an operator can confirm or correct.
- Invoice and receipt capture
- File and document validation
- Human review before release
- ReconcileReconciliation matches incoming transactions to your accounting records and queues exceptions for review.
- Transaction and invoice matching
- Exception queues
- Reconciliation acceptance
- Approve and closeA named reviewer approves the record or close task, with thresholds and sign-off rules agreed by finance.
- Approval thresholds and sign-off
- Review and release history
- Close workflow and period lock
- ReportFinance defines the figures and report layout, then checks the generated output against agreed examples.
- Management reporting packs
- Multi-entity rules and validation
- Scheduled report generation

Choose the right implementation for each accounting workflow
Package configuration, specialist services and custom modules each have a place in a finance system.
| Accounting requirement | Starting point | Scope we define with you |
|---|---|---|
| The general ledger and chart of accounts | Package configuration or a differentiated product | For standard bookkeeping, configure or integrate a suitable package. Where you are building an accounting product or need distinct ledger rules, we assess the core data model, validation and long-term maintenance before defining a custom build.Platform development and integrationOr book a meeting |
| Tax calculation and statutory filing | Specialist service or scoped custom logic | Integrate a tax or filing service where its coverage matches your requirements. Your accounting or legal advisers confirm the rules; where custom functionality is needed, we scope those rules and acceptance data explicitly.Regulated financial softwareOr book a meeting |
| Getting invoices, receipts and statements in | Capture tool or a reviewed custom workflow | Use a package or specialist capture tool when its formats and review process fit. Custom work can add document validation and an operator review step before data is released into the accounting system.Document-recognition case studyOr book a meeting |
| Reconciliation rules that are specific to you | Package rules or custom matching | Configure standard matching where it covers your records. We build custom reconciliation when your rules or review process need it, with sample transactions, exceptions and the expected result agreed before release.Bookkeeping-automation case studyOr book a meeting |
| Management reporting and consolidation | Package reports or a custom reporting layer | Use existing reports where their definitions and layout fit. A custom layer can combine agreed data sources and generate finance reports, with accounting definitions and consolidation rules tested against reference outputs.Data and BI engineeringOr book a meeting |
We integrate the general ledger you already run, because its rules are settled and packages implement them correctly. Around it we build invoice capture, reconciliation on your own rules and your monthly finance reporting. That is where custom work pays for itself.

Accounting workflows with reviewed inputs and verifiable output
Select the workflow to build or extend, from invoice capture through to management reporting.
Invoice and document capture
We extract fields from a PDF, scan or statement into structured records and flag missing or inconsistent data. An operator confirms or corrects the result before posting or import.
- Right when
- Documents need a reviewed route into the accounting system
Reconciliation and matching
We implement the matching rules finance defines and route unmatched transactions to an exception queue. Acceptance uses agreed examples of both matches and exceptions.
- Right when
- Your matching rules extend beyond package configuration
Approval and close workflow
We build approval thresholds, sign-off and close tasks around the people accountable for the figures. The workflow records each decision and the status of outstanding work.
- Right when
- Finance needs explicit approval and close responsibilities
Management reporting and consolidation
We generate reporting packs from agreed data definitions and layouts. Multi-entity consolidation is scoped with explicit accounting rules and validation for the entities involved.
- Right when
- Reporting needs agreed definitions across entities
Integration into the systems of record
We connect the accounting system to agreed billing, CRM or ERP interfaces, using an application programming interface (API) or file import. Reconciliation checks received and posted records against the expected result.
- Right when
- Accounting records arrive through separate systems
Accounting platform takeover and extension
We review the existing code, accounting data model and release process, then plan an extension that preserves usable work. Migration and reconciliation checks are defined before changing financial records.
- Right when
- An unfinished application needs a delivery plan

How a finance engagement runs around your close
We plan discovery, validation and release dates around the finance team's reporting and close calendar.
- Agree samples and acceptanceFinance supplies representative documents, transaction records and expected outputs. We review the rules and exceptions together so the first workflow has an agreed acceptance set.You getSample records, rules and expected outputs
- Confirm interfaces and release scopeWe check the package's API or import permissions and define what will be configured, integrated or built. The plan names the data sources, owners and maintenance responsibilities for the chosen workflow.You getA scoped implementation and integration plan
- Validate one workflow with financeWe build the agreed flow and compare its output with reference records. Finance reviews exceptions and approvals; tests cover the agreed matching or reporting rules before the workflow is released.You getA reviewed workflow and its acceptance results
- Roll out around the closeWe agree the migration checks, any parallel-run period and a release window with your team. Handover covers operation, reconciliation and the documentation needed to maintain the workflow.You getAn agreed rollout and operating documentation

A financial-platform takeover and back-office automation
- A bookkeeping platform, taken over mid-buildA London financial advisory firm asked us to extend an unfinished bookkeeping platform built on MySQL, ASP.NET MVC and C#. The work covered invoice matching, encrypted data and protected user accounts. Its Head of Product, in his 2017 Clutch review under our former Artelogic brand: "I was grateful to find a team that not only picked up an unfinished piece of software but also turned it around and improved it", and "I can't point to anything that Artelogic could do better".2017the year this client started with us
- Document recognition that doubled data-set throughputFor a Munich software company, we built a document-recognition tool with a C# backend and AWS microservices. An operator could release or correct the recognized data. Its CEO reported in his 2022 Clutch review: "Two people typing data into the database went about 5,000 new data sets per month. With this component, we're reaching twice the amount of data sets per month."2xtwice the data sets per month, the client's figure
- Report generation for a culture-analytics firmBarrett Values Centre, a culture-analytics firm in North Carolina, delivered reports in Word and PowerPoint. We built a C# application to generate them from prototypes and sample data. Automated tests let the client independently check the output against different data sets. See business process automation.

08Questions
Accounting software development: frequently asked questions
Use a package where standard bookkeeping and configuration meet your needs. Custom work fits distinct accounting rules, reviewed workflows or a differentiated product.
We compare workflow fit, interface access and maintenance responsibility before choosing the scope. That may mean configuring the existing ledger, integrating a specialist tool or building a custom module. A broader accounting-product build is scoped against its own data model and acceptance rules.
Yes, where the accounting system exposes suitable APIs or import routes and you have the required access.
Our accounting software integration scope defines what data can be read or written and how postings are validated. We agree test records and reconciliation rules with finance before release, including how duplicates and rejected imports are handled.
We price the accounting workflow and its integration scope using three engagement models.
- Time and materials, billed hourly and quoted per project.
- Fixed price, quoted per project against an agreed outcome.
- Team extension, billed monthly per team member.
The model depends on how firmly the scope is defined. Team extension has no recruitment or placement fee. Fixed-scope work includes a post-launch warranty, with its length agreed per contract.
Most engagements start within two to four weeks. The delivery schedule is agreed after the workflow, interfaces and acceptance data are scoped.
We plan releases around your close and reporting calendar. Migration checks and any parallel run are agreed for the particular workflow, with finance reviewing the output before the new process takes over.
We scope access, audit records and validation around the financial data and the controls your organization requires.
For build engagements, we agree least-privilege access with your technical contact, use read-only access wherever the work allows and make no production writes during discovery. Takeover and maintenance access is scoped separately.
unicrew holds ISO 27001:2022 and ISO 9001:2015, renewed through a multi-stage audit with Quay Audit UK. We have ISTQB-certified QA engineers; QA delivery is agreed per engagement.
Yes. We assess the code, accounting rules and data flows, then define what to extend and how the existing records will be preserved.
The first plan covers gaps in the handover, interface access and the tests needed to accept changes. It also sets out migration and reconciliation checks before financial records move to a revised workflow.
AI can help extract document data and propose transaction categories, with human review and validation against agreed examples.
We scope the review step before data is posted or imported. A proposed category is checked against your accounting rules; a generated explanation or report narrative must be checked against the underlying records. The first release is accepted on the accuracy and exceptions your finance team can verify. See AI integration services.
