Seven practical steps cut the selection risk and stop costly rework. Start by mapping what your business actually does and whether you must submit digital VAT records under Making Tax Digital for VAT. Then translate those needs into a features and integrations specification, test two or three shortlisted systems in parallel, and secure written SLAs before you sign. Follow the checklist below so you end a procurement with a system that handles payroll, bank feeds, payments and auditability without surprise costs.

1. Document your current operations and future plan

Lead with the answer. The single deciding fact is whether a package matches your daily workflows and your regulatory obligations. Begin with a mapped checklist of Core accounting workflows, who performs them, and where time is lost. Accountancy Age and smallbusiness.co.uk advise starting here because a mismatch at the outset is the common cause of expensive rip-outs later.

Make the checklist concrete. Capture how you raise and approve invoices, how you take payments, how you reconcile bank accounts, whether you hold inventory or run projects, and whether you need payroll and multi-currency handling. Also record current volumes and growth expectations so you can judge whether a basic package will suffice now or whether you need a system that scales.

Point is, worked example. A retail services firm that issues 300 invoices a month, runs a weekly payroll for 12 staff and reconciles three bank accounts will visibly outgrow a sole-trader package. If the business expects 20 percent annual growth, note that in the checklist so capacity and API limits are tested later.

2. Turn needs into a features and integrations specification

For you, features must not be a shopping list. They're pass-fail requirements. Across the guidance, essential accounting features to require are accounts receivable and payable, invoicing and templates, VAT handling and returns, bank feeds with automatic reconciliation, reporting and cashflow forecasting, and payroll if you have employees.

The Access Group’s product materials list additional modules mid-market firms commonly use: fixed assets, stock control, sales processing, purchasing, project accounting, integrations, reporting and cashflow forecasting. If your business processes cards, holds customer payment credentials, or links to third-party marketplaces, require native integrations or reliable APIs for payment processors, banks, ecommerce platforms and CRM systems.

TechRound’s fintech guide warns that when money movement, identity verification or card processing are part of the workflow, ask vendors about reconciliation logic, bank API behaviour under outage, KYC and AML support, and how the system records approvals and changes for later audit. Put those items in the specification as mandatory acceptance tests.

Worked example. Write a one-page spec that says: "Must import daily bank feeds, auto-match 95 percent of transactions, submit VAT returns electronically, and provide an API key for payment reconciliation with our gateway." Use that spec during live demos and trials so vendors must show the exact flows you use.

3. Evaluate security, compliance and vendor capability

Security matters early because it shapes procurement and contract clauses. TechRound sets out the technical controls you should verify: authentication and access control, encryption at rest and in transit, audit logs and tamper-evident records, monitoring and incident response, and third-party security certifications or audit reports where available.

For businesses in regulated verticals or handling cardholder data, demand evidence of PCI DSS, SOC 2 or equivalent assessments and clear obligations in the contract about who's responsible for data breaches. The fintech guidance also states that software alone doesn't make a business compliant. Policies, staff training and operating procedures must align with the technical controls the vendor supplies.

Usability and support are part of capability. Accountancy Age and smallbusiness.co.uk add that usability, mobility, and vendor training and support are material selection criteria because they determine adoption speed and the likelihood of human error in routine tasks. Check the vendor's documentation, training offer and support SLAs as part of the security and capability review.

Worked example. Require the vendor to supply the latest SOC 2 Type II report or a PCI DSS attestation letter where relevant. If a vendor can't provide these, add remedial controls to the contract or move the provider down your shortlist.

4. Compare cost structures, contract terms and scalability

Cost is rarely just the headline subscription. Smallbusiness.co.uk explains the main pricing variables: per-user fees, payroll add-ons charged per employee, module-based tiering, and discounts for annual prepayment versus monthly billing. Factor in implementation fees, data migration costs and any fees for API access or third-party connectors when comparing total cost of ownership.

The Access Group quotes market-facing prices for its finance software, stating entry commercial packages start at £97 per user per month, with an advanced accounting tier from £142 per user per month and bespoke quotes for project-based accounting, and it notes minimum user counts and minimum contract terms apply. Sources differ on typical entry-level cost expectations. Industry guides note that there are free or low-cost solutions for sole traders and micro-businesses, while vendor commercial materials for mid-market platforms list substantially higher per-user starting points.

When comparing, build a three-year model that includes: initial implementation, ongoing subscription, payroll per-employee charges, API or connector fees, and the estimated cost of additional modules you will need as you grow. Use that model to compare like for like.

Worked example. A firm evaluating a package at £97 per user with a three-user minimum and an alternative at £142 per user for ten users should calculate the total subscription plus implementation. Include a line for potential migration costs if the cheaper product fails to scale.

Trials matter because they're the only realistic check that a vendor delivers for your workflows. Both practical guides recommend running a trial or pilot that mirrors a real accounting cycle. Use the trial to import historical transactions, run a payroll cycle in parallel, validate VAT returns and electronic submissions, and exercise bank reconciliations against actual statements.

TechRound emphasises QA processes for fintech and payment flows, including regression, functional, and load testing where high transaction volumes or near-real-time balances matter. During pilots verify how the system handles failed payments, duplicate invoices, corrective journals and month-end reporting. Confirm data export formats and the ease of extracting a full dataset as an exit clause in case you need to replace the system later.

Worked example. Run two parallel months. Post identical transactions into your existing accounting system and the trial system. Reconcile both bank statements and compare the VAT returns generated. If totals differ, record the variance and ask the vendor to explain the reconciliation logic and the corrective steps.

Do not sign without written commitments. Before signing, obtain written service-level commitments for uptime, support response times and data restoration. Define the implementation timeline, responsibilities for data cleansing and mapping, acceptance criteria for the go-live and a rollback plan if key functionality doesn't perform in production.

Agree a training plan and documentation for your staff and set a review cadence to reassess whether the chosen tier still matches your needs as the business changes. Accountancy Age and smallbusiness.co.uk both emphasise that taking time up front to assess software options against current and future requirements reduces disruption and costs over the medium term.

Worked example. Include a contractual clause that the vendor will restore data from backups within a specified window and that support responses for critical issues arrive within four business hours. Tie a portion of final payment to acceptance criteria such as successful VAT submission and bank reconciliation for two consecutive months.

Reduce the choice to a shortlist of two or three vendors that meet your checklist. Prioritise live demonstrations that focus on your workflows rather than generic feature tours, and request references from similar-sized firms in your sector. For businesses with payment or identity workflows, prefer vendors with demonstrable experience in fintech implementations and with independent security attestations.

If a vendor's sales materials list industry-specific modules or case studies, probe the extent to which those modules are configurable versus requiring bespoke development. The Access Group materials offer a tailored quote and demo route for organisations that need bespoke feature mixes. Other vendors commonly provide trial accounts and tiered plans so you can test functionality before committing.

Worked example. Ask each shortlisted vendor to run a 90-minute demo using your one-page spec. Request a reference from a client of similar size and sector, and check whether the reference used out-of-the-box functionality or paid for bespoke development. That will reveal hidden costs and likely delivery timelines.

Procurement checklist

First, Two to three shortlisted vendors. Second, Live demos using your workflows. Third, Written SLAs for uptime and data restoration. Fourth, Proofs of compliance: SOC 2 or PCI DSS where relevant. Fifth, Trial that imports historical transactions and validates VAT submissions. Sixth, Clear exit terms and full data export in open formats.

TL;DR

First, Start by mapping core accounting workflows and check if Making Tax Digital for VAT applies. Second, Build a mandatory features and integrations spec; include bank feeds, VAT, payroll and payment APIs. Third, Verify security controls and request PCI DSS or SOC 2 evidence where applicable. Fourth, Model total cost of ownership, including implementation, migration and connector fees; note The Access Group’s published entry prices of £97 and £142 per user per month as market references. Fifth, Run parallel trials that cover a full accounting cycle before you sign.
