Accounts receivable software for engineering firms.

Paidnice gets engineering, architecture and planning firms paid phase by phase: reminders on every progress invoice, client statements, the interest your fee agreement allows and escalation before stop-work, from Xero or QuickBooks.

The accounts receivable toolkit for engineering firms

Every tool you need to get paid on time, running on your live Xero or QuickBooks invoices. Connect once and switch on what you need.

From the day you send it to the day it is paid

Every stage runs on your payment terms, automatically or after you approve it.

  1. Clients get a reminder before, on and after each progress invoice falls due, by email and text, from your own domain. They reply or pay from the link.

  2. Each client gets one statement on the day you choose, with every phase invoice and reimbursable across your projects and one total to pay.

    Explore statements →
  3. Paidnice adds the interest or late fee your fee agreement allows and posts it to your ledger. Key clients can stay exempt.

    Explore late fees →
  4. Paidnice reads each client reply, logs the promise or the question and drafts the next step. A project manager or partner approves each draft before it is sent.

  5. When reminders stop working, the account becomes a call, letter or stop credit task, with the full payment history attached, well before any stop-work notice.

    Explore escalations →
  6. Clients see every open invoice across your projects and pay by card or bank, or split a large fee into a payment plan. No login needed.

Built for how engineering firms get paid

Invoices go to accounts payable, reminders to the project manager.

Send each phase invoice to the client's AP inbox and the reminders to the project manager you work with.

  • Choose who gets invoices, reminders and statements
  • Replies stay in one email thread
  • Later reminders can come from a named director

Charge the interest your fee agreement allows, without a partner's call.

Paidnice adds the interest your fee agreement allows to overdue invoices and posts it to your ledger.

  • Set per client group
  • Key clients can stay exempt

In the UK, the Construction Act covers architectural, design and surveying work, so its statutory payment rights reach design firms.

Escalate before you have to invoke the stop-work clause.

When reminders run out, Paidnice escalates to a call task, a director email or a stop credit task.

  • Payer's record attached
  • The stop-work notice comes last

Know what is coming in, and who to call first

Paidnice turns your ledger into answers: the phase invoices due this week, the clients who pay late and the accounts a partner should call.

  • Expected payments, week by week, from your ledger
  • A credit score for every customer, from how they pay
  • Aged receivables for each customer, at a glance
  • A weekly report emailed to your team

How it works for engineering and architecture firms

How does Paidnice know which invoices to chase?
Engineering and architecture firms keep billing from their project tool, and Paidnice chases every invoice it pushes into Xero or QuickBooks. It sees every open invoice, its due date and its balance, then runs your reminder, statement and interest rules against them. When a payment lands in the ledger, the chasing for that invoice stops on its own.
Does it work with BQE Core?
Yes, engineering firms running BQE Core can keep billing exactly as they do now. BQE Core sends your invoices to QuickBooks Online once clients and projects are synced, and Paidnice picks them up from the ledger. The same goes for Total Synergy and WorkflowMax by BlueRock pushing into Xero, and Monograph into QuickBooks Online. Paidnice never touches the project management tool itself; it works from what lands in the ledger.
Can an engineering firm charge late fees on overdue invoices?
Engineering firms can charge the interest their fee agreement already allows, commonly 1 to 1.5 percent per month on overdue balances in the US, and Paidnice calculates it, adds it to the balance and posts it to your ledger. Whether and how much you can charge depends on your contract and your state, so check both.
What does Paidnice cost for engineering and architecture firms?
Engineering and architecture firms pay for Paidnice by invoice volume, not revenue. Essentials starts at US$69, £49 or A$99 a month, there are no contracts, and your first 20 actions are free.
What happens when a client disputes one invoice on a project?
Engineering firms keep the rest of a project billing on when a change-order invoice is contested. Pull that one invoice out of the policy by its reference, and the reminders and interest on it stop while every other invoice keeps its schedule. The same filter holds retainage lines that stay open until closeout.
What happens after the last reminder?
For engineering firms the ladder gets firmer without you drafting anything. Early reminders come from accounts at your own domain, and later sends carry the principal's name. Past that, Paidnice raises escalation tasks: a call with the payer's record attached, a director email, or a stop credit task while the balance clears. You decide how far it runs before anyone reaches for the stop-work clause.

Stop financing your clients' projects with unpaid fees.

Connect Xero or QuickBooks and Paidnice prepares draft policies for you. Nothing runs until you approve them.
