A clearer way to manage the business

Give repeat maintenance a familiar starting point

Keep standard inspection and servicing items ready to reuse. For another visit, copy the previous document and adjust the date, parts and work performed instead of recreating the customer's details.

Keep each site's records together

A commercial customer may have several premises. Use project records to separate locations and bring related documents and expenses together, making the relevant information easier to find before a service call.

Look beyond the invoice total

Installation, emergency call-outs and planned servicing have different cost patterns. Equipment, consumables, travel and subcontracted work can change the return on a job. Record those outgoings and compare them with collected payments, not only the headline estimate.

Questions about the software

Can I separate parts from service labor?

Yes. Add equipment, replacement parts and labor as distinct items with their own quantities and rates. The document then shows the basis of the total.

Can I reuse a maintenance invoice?

Yes. Copy the existing invoice and update it for the completed visit. Review the service date and replacement parts before sharing the new document.

Do I need to install the app?

No. You can sign in through the Web entry on this page, or download the iOS or Android app. Choose the option that fits your work.

Can I use my own branding?

Yes. Use your company information, logo and the application's available PDF design settings. Preview the document before sharing it.

Can I follow payments and outstanding balances?

Yes. Record payments against invoices and review the remaining balance. Reports reflect the business records saved in your account.
