The new iCertifi MintBooks integration turns every certificate you save into a ready-to-send invoice. Watch it happen.

Here is the bit of the job nobody enjoys: you have tested the installation, signed off the certificate and packed the van, and there is still an invoice to raise later from memory. That is where money quietly leaks away. The iCertifi certificates app now fixes it. Save a certificate and a matching draft invoice appears in MintBooks a second later – client, job and price already filled in. It is the fastest electrician invoicing app workflow we have built, and you barely have to lift a finger.

The description carries the certificate type and address, and the amount comes straight from the rate you set for that certificate type. It lands as a draft, so nothing reaches your customer until you say so. Want to tweak the price, add a call-out charge or reword a line? Do it before you send. It works across every certificate type – EICRs, EICs, Minor Works, EV charger certs – and it works offline too.

Green means the draft is ready to send. Amber means it synced but needs a price for that certificate type. Grey means it is saved offline and waiting – it will send itself the moment you get signal back, in the plant room or out of it. Red means a sync did not land; one tap retries it. Re-syncing is always safe: the server matches each certificate by its reference number and updates the existing record, so you will never end up with two invoices for one job. Need to pull in older work? Settings > MintBooks > Sync From lets you back-sync Last Month, Last Year or All Time in one tap.

The certificate link is one small part of a much bigger tool. MintBooks is a complete UK bookkeeping, tax and quoting platform built from the ground up for small businesses. You can send branded quotes that clients accept online with a digital signature – name, IP address and timestamp recorded for audit – then convert an accepted quote into an invoice in one click. Its AI receipt scanner reads the vendor, amount, date and VAT straight off a photographed receipt and maps it to the correct HMRC Self Assessment box, and it tracks mileage at HMRC rates.

Tax is handled end to end. The 9-box VAT return is calculated automatically from your invoices and expenses and submitted directly to HMRC under Making Tax Digital, with Standard, Cash and Flat Rate schemes supported and records locked after submission. For the trade there is full CIS support, with automatic labour and materials splits and 20% or 30% deductions worked out for you. Underneath sits genuine double-entry bookkeeping – chart of accounts, journal entries, period locks – alongside profit and loss, balance sheet and cash flow reports, project job-costing, time tracking and custom automations. It covers sole traders, limited companies, partnerships and LLPs, gives your accountant read-only access with no per-user fee, and keeps everything under AES-256 encryption with a 6-year audit trail.

Can I edit the invoice before it goes out? Always. Every sync creates a draft, so you can change the price, add line items or edit the description before it reaches your customer.

What if I sync the same certificate twice? The server matches it by reference number and updates the existing record. You will not end up with duplicate invoices.

Does it work with every certificate type? Yes – EICRs, EICs, Minor Works, EV charger certificates and the rest all sync the same way.
