An invoice app for independent consultants.

Strategy, management, technical, marketing, executive coaching - independent consulting is a high-fee, low-volume business. You need to send invoices that look like they cost something, track expenses meticulously, and have clean records when the IRS asks. VioBusiness does that, without a subscription bill arriving every month.

i.The consultant invoice problem

Most consultants we've spoken to fall into one of three setups:

• Word/Pages template. Looks fine. Manual everything. Numbering drifts. PDF quality is acceptable but unmistakably a document, not an invoice.
• FreshBooks or Wave. Works but $20-$60/month for 10-15 invoices per year feels indulgent.
• QuickBooks Self-Employed. Tax-focused but the invoice template is generic and the cross-sell pressure is constant.

VioBusiness is none of the above. It's a phone-first app that sends professional invoices with your logo, your brand color, your business address, and a clean PDF the recipient takes seriously. Paid once.

ii.What makes it consultant-friendly

• Custom brand color and logo on every invoice and contract. Set once in Business Profile; every PDF reflects your brand.
• Quote-to-invoice conversion. Send a proposal, win the engagement, convert to an invoice with one tap. Line items, dates, tax, notes carry over.
• Long-form contracts. VioBusiness includes a dedicated Contract document type with introduction, scope, timeline, and terms - the format consultants actually use to scope client engagements.
• Multi-currency. International clients pay in USD, GBP, EUR, or whichever currency you bill. Records keep the original.
• Recurring retainers. Set a monthly retainer once; it issues automatically. Useful for ongoing advisory clients.
• Expense tracking with receipt photos. Travel, software, books, professional development - log them, attach receipts, claim on Schedule C.
• Payment instructions on every invoice. Add your bank ACH, Wise email, Stripe link in the Business Profile and it appears on every invoice.

iii.The consultant tax picture

For a US-based independent consultant working as a sole proprietor or single-member LLC:

• Most consulting services aren't sales-taxable in most states. Default to 0% sales tax on invoices unless your specific state taxes professional services.
• Income gets reported on Schedule C with your 1040.
• Quarterly estimated tax payments are typically required - keep an eye on the dashboard for income trends.
• Self-employment tax (15.3%) applies to net business income above the standard threshold.
• Health insurance, retirement contributions (SEP-IRA, Solo 401k), and a portion of phone/internet/office are deductible.

VioBusiness records support all of these via CSV export. Your CPA gets the source data; the deductions and filings happen in their software.
