Who this is for
Solo painters and small crews doing residential and small commercial work.
Who this is not for
Painting spans a wide range from solo house-repaint work to enterprise multi-site industrial contracts. Billgami sits at the solo-crew end.
For crew scheduling, Jobber or Housecall Pro. For accounting, QuickBooks. Billgami stays in the estimate and invoice paperwork lane.
Walk the property, price by room or wall area, itemize labor + paint + prep + trim, send the PDF estimate, convert to an invoice on completion.
Add the client with contact info and property address. Repeat property-management clients with multiple buildings, save each address so the paperwork stays clean.
Build the estimate the way you quote: per room, per wall area, or per total square footage. Add prep work, primer coats, top coats, and any specialty labor as separate line items.
Save common services in your library: labor per hour, prep + patch, primer + first coat, second coat, trim detail, cabinet refinish, deck stain. Drop into any estimate with one tap.
Preview the estimate, share the PDF through email or text before you leave. Works offline. Client gets a print-clean document they can save or forward for approval.
When painting completes, one tap turns the estimate into the invoice. Adjust actual hours or paint gallons used if the job differed from the quote. Send the invoice PDF the same way.
Client pays through check, Zelle, Venmo, or their preferred method. Billgami never processes payment. You mark the invoice paid when the money lands.

Six things Billgami ships for painting workflows. Honest scope: this is not a scheduling suite or an industrial paint calculator. It is the estimate and invoice paperwork layer for solo painting work.
Save clients and properties for reuse
Property-management repeats, HOA jobs, and residential referrals all get saved. Property address, access notes, and paint-preference notes travel with every future estimate or invoice.
Save labor, paint, prep, and trim as reusable line items
Save your service library the way you actually quote: labor per hour, prep + patch, primer + first coat, second coat, trim detail, cabinet refinish, deck stain, exterior wash.
Estimate by room, wall area, or square footage
Different jobs price differently. Interior repaints usually go by room. Exterior work often prices by wall area or square footage. Cabinet refinish is per unit. Billgami lets you build any of these structures per job.
Send professional PDF quotes from the property
Estimate at the site, share the PDF before you leave. Works offline; PDF generation does not need cellular. Print-clean document readable on phone or desktop.
Convert an approved estimate to an invoice in one tap
When the paint dries and the job wraps, one tap turns the estimate into the invoice. Adjust actual hours or paint gallons if the job differed. Send the invoice PDF the same way.
Track paid, unpaid, and partial manually
Painters often take a deposit for larger jobs and get paid on completion. Billgami tracks the status manually so deposits, progress payments, and final payments all get recorded. No card processing.
The r/painting subreddit and adjacent trade forums have running conversations about invoice tools painters actually use. Three consistent patterns show up.
Pattern 1: solo painters resist subscription pricing. In threads about invoice tools, the most common complaint is not features but recurring cost. Painters who invoice 10-30 jobs a month feel a monthly subscription eats into margin. Threads consistently recommend one-time-purchase tools or spreadsheet workflows over subscription apps for solo work.
Pattern 2: painters want line items that match how they quote. Room-by-room pricing, wall-area pricing, and specialty-work pricing (trim, cabinet refinish, deck stain) all need to fit inside the same app. Rigid template tools that force one pricing structure get abandoned.
Pattern 3: painters underestimate paint materials in about 20-30% of jobs (aggregated from Reddit and PDCA discussions). Being able to adjust actual materials on the invoice after the job is the difference between eating the cost and getting paid for what you used. Billgami's one-tap estimate-to-invoice conversion with editable line items is built for this reality.
Billgami's painter positioning is grounded in three sources. First, BLS occupational data on Painters, Construction and Maintenance (~250K workers, 2024). Second, PDCA industry data on typical painting cost structures and job-size ranges. Third, Reddit r/painting and r/HomeImprovement discussions about invoice tools painters actually use. The consistent pattern: painters resist subscription pricing on paperwork tools, want flexible line-item structure that matches room/area/specialty pricing, and often adjust materials on the invoice after underestimating during the quote. Billgami's six features are built directly against these specific patterns.
Solo painters already pay for paint, brushes, drop cloths, and truck maintenance. Billgami is one App Store purchase. Own the app, keep your estimate and invoice history, never pay again for the paperwork layer.
Locked pricing
Free tier + Lifetime option ($249.99)
One purchase covers the full painter workflow: unlimited estimates, unlimited invoices, unlimited clients and properties, PDF export, offline mode, manual status tracking.
See full pricingvs Housecall Pro
Housecall Pro is a full field-service platform: dispatch, scheduling, customer records, marketing, payments. Built for growing painting companies with crews. For a solo painter or 2-person crew, most of that surface area is unused overhead paid for monthly. Solo painters consistently mention paying for features they never use.
vs Joist
Joist is well-known among contractors and used by some painters for its estimate-to-invoice workflow. Subscription-priced with integrated payments. For painters who want the same paperwork flow without the subscription or payment-processing overhead, Billgami covers it.
vs QuickBooks
QuickBooks handles accounting and tax. Painters with employees or complex tax needs use it. Not designed for fast mobile estimate creation from the property. Billgami handles on-site paperwork; QuickBooks (if needed) handles accounting behind it.
Simple Invoice App
The core mobile invoice workflow behind the painter page.
Estimate & Quote Maker
The estimate half of the painter workflow, in depth.
For contractors
The larger-project sibling for trades.
For handymen
The repair-work sibling for solo service pros.
For landscapers
Outdoor service with materials line items.
Pricing
Free, subscriptions, or lifetime ($249.99). Pick what fits.
Estimate by room or wall area, itemize labor and paint, send PDF quotes from the property, and get paid the way you already work. Free tier plus a lifetime option ($249.99) if you want to skip renewals.
