In brief

Invoicera helps contractors create outgoing invoices from agreed jobs, completed phases, milestones and approved time. Finance can keep the billable source, customer terms, reviewer and receivable status connected as each invoice moves forward. It supports billing control for growing contracting teams; it does not manage field scheduling, materials procurement or supplier bills.

Recognise the work

Completed work and billable work are not always the same state.

A team can finish a phase while the customer confirmation, approved variation or internal review is still missing. Billing needs to distinguish physical progress from the commercial event that permits an invoice.

  1. 01

    The job is marked complete without a billing trigger

    Operations finished the work, but finance cannot see which agreed phase should now be invoiced.

  2. 02

    A variation changes the outgoing amount

    The new value is known locally but has not reached the reviewer responsible for the invoice.

  3. 03

    Payment status is tracked away from the job

    The team cannot connect an open balance to the stage and customer conversation that created it.

Estimating and invoicing

Estimating and invoicing software for trade contractors.

Most contractor jobs start with an estimate. Invoicera turns the accepted estimate into an invoice, so the agreed scope and price carry through to billing instead of being retyped. Contract billing then follows the agreed stages, and approved variations go on as their own lines.

  1. 01

    Estimate to invoice

    Create a quote or estimate and convert it into an invoice when the customer accepts it.

  2. 02

    Contract billing by stage

    Bill a fixed contract price in agreed stages, or trigger an invoice when a milestone is completed (milestone triggers from the Grow plan).

  3. 03

    Service and maintenance contracts

    Bill a maintenance or service contract on a weekly, monthly, quarterly or annual schedule with its start and end dates.

Time and material billing

Time and material billing for electrical and other trade contractors.

Electrical contractors often price service calls and smaller jobs as time and material: hours at an agreed rate, plus the parts used. The billing has to apply the right rate to approved hours and keep labour and materials explainable to the customer. Time-and-materials billing is included from the Grow plan.

  1. 01

    Rates by role or task

    Set different rates for roles such as an electrician and an apprentice, or for a type of task, and apply them to the hours billed.

  2. 02

    Approve hours before billing

    Review timesheets before they reach an invoice, so only approved hours are charged.

  3. 03

    Materials on their own lines

    Add the parts and materials the customer agreed to pay for as separate invoice lines. Invoicera bills them; it does not buy or stock them.

  4. 04

    Log time away from the office

    Log time against a project in the iPhone or Android app and create the invoice from the timesheet.

How it works

Move from accepted stage to resolved invoice.

The useful record keeps the commercial trigger visible without turning the billing product into a field-management system.

  1. 01

    Confirm

    Identify the agreed job, phase, milestone or time record that the customer terms permit billing.

  2. 02

    Approve

    Check the outgoing amount, variation and customer details before the invoice is delivered.

  3. 03

    Collect

    Retain the reminder stage, customer response and payment match beside the resulting invoice.

A practical decision rule

Use the commercial trigger - not a general completion label.

A job event becomes billable only when it matches the agreed milestone, phase or approved time condition.

Worked example

A $40,000 job billed by accepted stage

Mobilisation
20% = $8,000
Phase one accepted
35% = $14,000
Approved variation
$2,500
Current outgoing invoice
$16,500
The invoice reflects the accepted phase and approved variation, while the uncompleted job balance remains outside the current billing event.

Customer perspective

What customers say about working with Invoicera.

My contractor business moved away from a manual invoicing process. Invoicera made invoicing simpler, which leaves me more time to help clients.
Jacob Davis
Late payments made cash flow difficult to manage. Invoicera gives me notifications when clients have not paid, so I can respond and keep the business moving.
Cyrel Hayward
Invoicera has streamlined our billing operations and helped us reduce manual effort. We particularly value its automation, ease of use, and professional invoicing experience. It’s a great solution for growing businesses, and we’re happy to recommend it.

Questions buyers ask

Know where this fits.

Each answer stands on its own, including the boundary of what Invoicera does and does not do.

What can contractors invoice through Invoicera?

Contractors can create outgoing invoices for agreed jobs, scheduled phases, accepted milestones and approved time. The invoice should follow the commercial terms rather than a general statement that work is complete. Invoicera keeps the billable source and outgoing controls connected, while the contractor remains responsible for confirming completion and customer acceptance.

Can a contractor bill a project in stages?

Yes. A project can be billed against defined milestone or phase amounts when the relevant condition is met. The team should retain the agreed percentage or amount, the acceptance event and the reviewer for each stage. This creates an explainable billing schedule without implying that Invoicera manages the underlying field work.

Does Invoicera manage materials or supplier bills?

No. Invoicera does not run procurement, inventory, supplier-bill approval or payment activity. Contractor pages cover outgoing customer billing based on agreed work. Material or external-cost information may inform a customer invoice only when the business has already determined the billable line and entered it under the applicable customer terms and review process.

How are approved job variations handled in billing?

Treat an approved variation as a distinct billable source with its reason, effective amount and reviewer. Add it to the appropriate outgoing invoice only after the commercial decision is clear. Keeping the variation separate from the original phase helps finance explain the changed total and prevents an informal job update from becoming an unreviewed charge.

How does contractor billing connect to payment follow-up?

After the outgoing invoice is sent, the receivable can retain its due date, reminder stage, customer response, exception and payment-matching status. Routine overdue balances can follow a configured reminder ladder, while a customer question about a job stage should remain visible for human review instead of continuing as ordinary automated follow-up.

Can Invoicera work as electrical contractor time and material billing software?

Yes, for the billing step. From the Grow plan, an electrical contractor can bill approved hours at rates set by role or task, add the agreed parts and materials as separate invoice lines and approve timesheets before they reach an invoice. Invoicera does not schedule crews, buy materials or hold stock.

Does Invoicera handle both estimating and invoicing?

Yes. A contractor can create a quote or estimate, send it to the customer and convert it into an invoice once it is accepted, so the agreed scope and price carry through. The free estimate template and estimate generator help with a one-off estimate; Invoicera keeps the estimate and the invoices that follow it in one billing record.

How should we choose invoicing software for contractors?

Test it on a real job. Check that an accepted estimate becomes an invoice without retyping, that stages or milestones bill at the agreed amounts, that approved variations stay on their own lines, that hours bill at the right rate by role or task, and that someone reviews a changed invoice before it is sent. Then check how open balances are followed up after delivery.
