What is the best invoicing app for solar installers?
SMASH handles complex solar installation invoicing — panels, inverter, racking, labour, and STC rebates all on one invoice — from a voice description. Set your equipment catalog, crew rates, and STC rebate formula once. Describe the system out loud and SMASH builds a fully itemised, GST-compliant invoice from your phone in under 60 seconds, ready for the client on commissioning day.
The solar installer invoicing problem
Sound familiar? You're not alone.
High-value invoices with many components
Panels, inverter, racking, isolators, labour, STC rebate — manually entered line by line every time.
STC rebate deduction
The rebate reduces the client's payment. Showing it correctly on the invoice takes careful formatting every job.
Commission and installation split
Commissioning on a separate day, invoiced separately. Remembering what was on the first invoice.
Sub-contracting for solar companies
Labour-only invoices to the solar company in a different format — but the same manual hassle.
Battery storage add-ons
Different pricing, different rebate structure. Still expected to be on the same professional invoice.
Finance application invoices
Clients using solar finance need a specific invoice format. Getting it right matters for approval.

In practice
Just describe the job
SMASH turns your voice into a complete, priced invoice. Here's what that looks like for solar installers.
You say
""6.6kW system at the Dee Why property. 18 panels LG 370W, SolarEdge 5kW inverter with optimisers, standard residential install. Two crew, one day. Deduct 32 STC rebate.""
SMASH invoices
6.6kW solar install — 18× LG 370W + SolarEdge 5kW + install (2 crew) − 32 STC rebate = $6,890.00 + GST
You say
""Sub-contract install labour for SolarPath at the Liverpool job. 10kW system, two crew, two days. Bill at the commercial sub-contract rate.""
SMASH invoices
Solar install labour — 2 crew × 2 days @ $450/crew-day = $1,800.00 + GST
You say
""Battery storage add-on at the existing Hurstville system. Tesla Powerwall 2, supply and install, 4 hours labour.""
SMASH invoices
Battery storage install — Tesla Powerwall 2 + 4 hrs @ $130/hr = $10,120.00 + GST
You say
""Residential 10kW system at Penrith. 25 panels Jinko 400W, Fronius Symo 10kW inverter, standard racking. Two crew, one day. Deduct 48 STC rebate.""
SMASH invoices
10kW solar install — 25× Jinko 400W + Fronius Symo + racking + install − 48 STC = $9,250.00 + GST
Built for the trade
Built for how solar installers run
STC rebate as a line item
Add the STC rebate as a negative line item. Describe the number of STCs and SMASH deducts the correct amount from the total.
Panel, inverter, and racking pricing
Set your equipment prices in the catalog. Mention brand, model, and quantity — SMASH prices it all as separate line items.
Crew and labour rates
Set your crew day rate. Mention crew size and days — SMASH multiplies correctly without you doing the maths.
Battery storage pricing
Add battery system pricing to your catalog — Powerwall, Sungrow, Enphase. Mention the unit and SMASH prices supply and install.
Sub-contract invoice format
Invoice solar companies for labour-only sub-contract work at your agreed rate. Same voice input, different client.
Quote before, invoice on commissioning
Quote the system before install. Invoice on commissioning day. Both from the same voice input — no re-entering anything.
