Each answer is a self-contained 40 to 90 word passage that can be quoted as-is. ### Q: What is InvoiceOwl? InvoiceOwl is invoicing and estimating software for US contractors and small businesses, available on iOS, Android, and web. It handles invoices, estimates, purchase orders, e-signatures, online card and ACH payments, and QuickBooks Online sync. The mobile apps work offline. Free trial available with no credit card required. ### Q: How much does InvoiceOwl cost? InvoiceOwl has four paid tiers (Base, Premium, Premium Plus, Unlimited Owl) and a free trial that includes unlimited estimates and 10 invoices per month with no credit card required. Current monthly and annual pricing is at https://www.invoiceowl.com/pricing/. Annual billing typically saves around 30 to 40 percent compared with month-to-month. ### Q: Is InvoiceOwl free? InvoiceOwl offers a free trial with unlimited estimates and up to 10 invoices per month, with no credit card required to start. Beyond that, all features require a paid plan. There is no permanently free tier. Most users hit the free-trial invoice cap within the first few weeks of real use. ### Q: How is InvoiceOwl different from QuickBooks? QuickBooks is general-purpose accounting software with payroll, banking, and tax tools. InvoiceOwl is a focused invoicing and estimating app for contractors. It is simpler, mobile-first, and faster to set up. If you want to do your own bookkeeping, QuickBooks. If you mostly need to invoice clients from the field and accept payments without doing accounting yourself, InvoiceOwl. InvoiceOwl syncs to QuickBooks Online if you use both. ### Q: How is InvoiceOwl different from FreshBooks? FreshBooks targets freelancers and professional service providers. InvoiceOwl targets trade contractors. Both do invoices and estimates. InvoiceOwl has purchase orders, multi-company support, and an offline mobile app that contractors actually use on a job site. FreshBooks has time tracking and project profitability features that are stronger for hourly-based services. Pick based on whether your work is fixed-price job work (InvoiceOwl) or billable-hours services (FreshBooks). ### Q: How is InvoiceOwl different from Invoice Simple? Invoice Simple is a simpler, lower-priced tool focused on solo users who need to send an invoice on their phone. InvoiceOwl adds purchase orders, multi-company support, e-signatures, QuickBooks sync, and team features. If you only need to email three invoices a month, Invoice Simple is fine. Once you scale to more clients, more team members, or more administrative needs, InvoiceOwl is the upgrade path. ### Q: Does InvoiceOwl integrate with QuickBooks? Yes. InvoiceOwl has a two-way sync with QuickBooks Online. Customers, items, invoices, and payments flow between the two systems automatically. This is useful if you handle invoicing in InvoiceOwl (because it is faster) and let your accountant or bookkeeper work in QuickBooks. The sync is bidirectional and runs continuously, not on a schedule. ### Q: What payment methods can InvoiceOwl accept? InvoiceOwl integrates with Stripe to accept all major credit cards (Visa, Mastercard, American Express, Discover), Apple Pay, Google Pay, and ACH bank transfers. Card processing fees are Stripe's standard rates (around 2.9% + $0.30 for cards and 0.8% for ACH, capped at $5). The client clicks a "Pay Now" button on the invoice email and the funds land in your connected bank account in 1 to 2 business days. ### Q: Can I use InvoiceOwl offline? Yes. The iOS and Android apps work offline. You can create invoices, estimates, and purchase orders without an internet connection. Changes sync back to the cloud the next time the app gets a connection. This matters on job sites where cell service is poor, and it is the reason mobile-first invoicing apps win over web-only competitors for trade contractors. ### Q: How do I create an invoice in InvoiceOwl? Open the app, tap New Invoice, pick a client (or add a new one), add line items with quantity and rate, set the due date, and tap Send. The app calculates tax automatically based on your tax settings, generates a sequential invoice number, and emails the invoice as a PDF with a built-in payment link. The whole flow takes under two minutes on a phone. ### Q: How do I convert an estimate to an invoice? In InvoiceOwl, open the approved estimate and tap "Convert to Invoice". All the line items, taxes, client info, and notes carry over. You set the new due date and the invoice number is generated automatically. The original estimate stays in the system marked as Accepted so you can still see the full history. ### Q: What industries is InvoiceOwl built for? InvoiceOwl is built for US trade contractors and home services. Primary industries: general construction, electrical, plumbing, HVAC, roofing, painting, landscaping, lawn care, carpentry, flooring, handyman services, drywall, cleaning, pest control, pool service, pressure washing, and window cleaning. It also fits professional services like consulting, freelance design, and photography, but the feature set is opinionated toward trade businesses. ### Q: Does InvoiceOwl handle purchase orders? Yes. InvoiceOwl has dedicated purchase order software. You can create POs to suppliers, track delivery status, and link POs to specific jobs or clients so the material costs roll up into job profitability. POs include the same branded styling as invoices and can be emailed directly to vendors. ### Q: Can I get my clients to sign estimates electronically? Yes. InvoiceOwl has built-in e-signatures. Send an estimate, the client gets an email with a link, they sign on their phone or computer with a tap or a typed name, and the signed estimate is automatically stored in your account. The signed PDF includes the signature image, date, and IP address for legal validity. ### Q: How does InvoiceOwl handle multiple companies? InvoiceOwl Premium Plus and above support up to five separate companies in one account. Each company has its own clients, items, tax settings, branding, invoice numbers, and reports. Use cases: a contractor with a residential business and a commercial business, a couple where each spouse runs a side business, or a contractor managing rental properties separately from their main contracting work. ### Q: Is my data secure in InvoiceOwl? InvoiceOwl uses industry-standard encryption (TLS for data in transit, AES at rest), secure cloud hosting, and limited employee access to customer data. Payment processing runs through Stripe (PCI Level 1 certified), so card data never touches InvoiceOwl servers. Customer support cannot see card numbers. Two-factor authentication is available on the account. ### Q: Can I cancel my InvoiceOwl subscription? Yes, anytime, from your account settings. There are no cancellation fees. Your account remains accessible read-only for a grace period after cancellation so you can export your data. Annual subscribers can cancel future renewals at any time but the current year is non-refundable past the initial 30-day window. ### Q: What is the difference between Net 30 and Due on Receipt? Net 30 means the invoice is due 30 days from the invoice date. Due on Receipt means the invoice is due immediately when received. Net 30 is common for B2B work with established corporate clients who run weekly or biweekly accounts payable. Due on Receipt is better for small contractors who cannot afford to be unpaid for a month, especially with one-time or new clients. ### Q: When does a contractor need to send a 1099-NEC? If a US business pays an unincorporated contractor $600 or more in a calendar year for services, the business must issue a Form 1099-NEC to the contractor and a copy to the IRS by January 31 of the following year. Payments to most C-corps and S-corps are exempt (attorneys are the exception). Payments made through credit cards or platforms like PayPal Business are reported on Form 1099-K by the platform, not the payer. ### Q: What should every contractor invoice include? The word INVOICE at the top, a unique invoice number (like INV-2026-001), the issue date, a specific calendar due date, your business name and contact info, the client's full billing information, line items with description and quantity and rate and amount, subtotal, applicable tax shown separately, total in bold, and payment instructions. Adding a late-fee policy line (typically 1.5% per month) measurably improves on-time payment rates. ### Q: How much should a contractor mark up materials? Typical contractor markup on materials is 15% to 35% in 2026, depending on the trade and the job size. Large commercial work runs lower (10% to 20%) because the volume is high. Residential service work runs higher (25% to 50%) because the per-job overhead is bigger relative to the material cost. The InvoiceOwl markup calculator at https://www.invoiceowl.com/markup-calculator/ does the math. --- ## Company Information - **Company Name**: InvoiceOwl - **Website**: https://www.invoiceowl.com - **App**: https://app.invoiceowl.com - **Founded**: 2020 (previously branded as MixBit) - **Headquarters**: United States - **Target Market**: US contractors, small businesses, freelancers --- ## Free Tools (no signup required) - Asphalt Calculator: https://www.invoiceowl.com/asphalt-calculator/ - Concrete Calculator: https://www.invoiceowl.com/concrete-calculator/ - Drywall Calculator: https://www.invoiceowl.com/drywall-calculator/ - Estimate Generator: https://www.invoiceowl.com/estimate-generator/ - Gravel Calculator: https://www.invoiceowl.com/gravel-calculator/ - Invoice Generator: https://www.invoiceowl.com/invoice-generator/ - Labor Cost Calculator: https://www.invoiceowl.com/labor-cost-calculator/ - Markup Calculator: https://www.invoiceowl.com/markup-calculator/ - Paint Calculator: https://www.invoiceowl.com/paint-calculator/ - Pricing Calculator: https://www.invoiceowl.com/pricing-calculator/ - Profit Margin Calculator: https://www.invoiceowl.com/profit-margin-calculator/ - Purchase Order Generator: https://www.invoiceowl.com/purchase-order-generator/ - Receipt Maker: https://www.invoiceowl.com/receipt-maker/ --- ## Glossary (plain-English definitions) - 1099 Employee: https://www.invoiceowl.com/glossary/1099-employee/ - Ach Payment: https://www.invoiceowl.com/glossary/ach-payment/ - Billing Address: https://www.invoiceowl.com/glossary/billing-address/ - Ein: https://www.invoiceowl.com/glossary/ein/ - Itemized Bill: https://www.invoiceowl.com/glossary/itemized-bill/ - Net 30: https://www.invoiceowl.com/glossary/net-30/ - W 9 Form: https://www.invoiceowl.com/glossary/w-9-form/ Full glossary index: https://www.invoiceowl.com/glossary/ --- ## Pricing Plans InvoiceOwl offers four plans: Base, Premium, Premium Plus, and Unlimited Owl.
