Best Accounts Receivable Software for UK Construction Companies (2026)

Why AR Is Harder in Construction

Construction invoicing is not like standard B2B invoicing. Most sectors raise an invoice and wait for payment. Construction companies deal with:

• Progress billing — invoices tied to project milestones, not delivery of a single product
• Retention (5–10%) — a portion of each invoice withheld until project completion, creating a permanent receivable balance
• Long payment cycles — contracts specify 30 days, but 60–90 days is common due to internal approvals and cash flow constraints up the supply chain
• Disputed valuations — disagreements over work completed create invoice disputes that standard reminder sequences can't resolve
• Supply chain complexity — main contractors managing subcontractor payments while managing their own client receivables simultaneously

The result: UK construction companies carry some of the highest overdue receivable balances of any sector.

2026 Retention Reform — What Changes

The UK government's Commercial Payments Bill, introduced into Parliament in May 2026, proposes to ban cash retentions in construction contracts. From April 2025, businesses with qualifying construction contracts are already required to report on their use of retention clauses.

If the retention ban passes, surety bonds and defects bonds will replace the traditional 2.5–5% cash holdback — freeing up working capital across the supply chain but requiring new processes for tracking and releasing retention equivalents. Construction businesses need AR software that can adapt to these changing payment structures.

What to Look for in Construction AR Software

• Flexible invoice structures — support for progress claims, milestone billing, and retention tracking
• Multi-channel outreach — construction project managers often respond better to WhatsApp or SMS than email
• Fast setup — site-based teams can't afford lengthy software implementations mid-project
• Integration with Xero, QuickBooks, or Sage — the most common accounting platforms for UK construction SMEs
• AI risk scoring — flag which clients are most likely to withhold payment before the invoice is due

Best AR Software for UK Construction Companies 2026

#1 Equisettle — Best for Proactive Collections Across the Supply Chain

From £49/month | Free trial | 48-hour setup

Equisettle's predictive AI is particularly valuable in construction, where payment delays tend to cluster around specific client types and project phases. Its model scores invoice payment risk up to 14 weeks before the due date — giving project finance teams early warning on which progress claims are most likely to be disputed or delayed.

Multi-channel outreach (email, SMS, and WhatsApp) suits the way construction project managers and site teams communicate. Native integrations with Xero, QuickBooks, FreeAgent, and Sage cover all the accounting platforms common in UK construction SMEs.

Best for: UK construction SMEs and subcontractors wanting proactive, AI-led collections with WhatsApp outreach.

#2 Chaser — Best for Escalation Workflows on Disputed Invoices

From £199/month | Free trial

Chaser's rule-based escalation sequences are well suited to construction's long payment cycles — you can configure different reminder sequences per client, per contract type, and per invoice age. Its optional Care add-on (human credit control team) is useful when a disputed valuation needs a phone call rather than another email.

Email only — no WhatsApp or SMS. Supports Xero and QuickBooks; no FreeAgent or Sage.

Best for: Established contractors with dedicated credit control teams needing structured escalation and optional human collections support.

#3 Satago — Best for Credit-Checking Subcontractors and Clients

From £45/month | Free tier

Satago's built-in Experian integration is useful in construction for assessing the creditworthiness of new clients or subcontractors before committing to a contract. Running a credit check at the estimate stage — rather than after 90 days of unpaid invoices — prevents the most damaging AR situations in the sector.

Email-only outreach. Integrates with Xero, QuickBooks, and Sage.

Best for: Construction businesses that want to assess client credit risk before work begins, especially for larger project values.

#4 Credit Hound — Best for Large Main Contractors with Dedicated Credit Teams

From £500+/month | Custom pricing

Credit Hound is built for large businesses with dedicated credit control departments — which describes major main contractors better than SME subcontractors. Its feature depth (credit limit management, debtor risk scoring, detailed workflow control) suits the complexity of managing receivables across dozens of active projects and hundreds of retention balances simultaneously.

Best for: Main contractors with turnover above £20M and a dedicated credit control function.
