Stop leaving billable hours on the table
Most consultants lose 8–12 billable hours per month to forgotten time entries, vague invoices, and clients who push back on charges they don't understand. FlowQi connects your work, your time, and your invoices — so every hour you deliver gets paid.
You deliver more than you bill.
I billed 35 hours but I know I worked at least 48. The rest just disappeared because I logged them too late.
A client pushed back on my invoice. I couldn't show them a clear breakdown of what I did and when. It was embarrassing.
I have three different billing models across five clients — retainers, hourly, and fixed-fee projects. I track all of it in three different spreadsheets.
My invoicing is always two weeks late because I have to piece together the hours from email, calendar, and notes before I can send anything.
I know one of my clients is not profitable, but I can't prove it because I don't have clean data on what I actually spent on them.
Consultants don't lose clients over bad advice. They lose money because the link between the work they do and the invoice they send is broken.

For the consultant who needs to decide.
Stop losing revenue to forgotten entries. FlowQi captures hours as you work — so your invoice reflects what you actually delivered.
Send invoices with a full, itemized breakdown. Clients see exactly what they're paying for — disputes disappear.
Retainers, hourly, fixed-fee — manage every billing model in one place. No more tracking three clients in three spreadsheets.
No IT setup. No implementation project. Most consultants are fully running within days, not weeks.
Plan hours. Log hours. Invoice what you delivered.
Set the budget — hours and rate per project
Every engagement gets a planned hour budget and an hourly rate. 40h at €150/h. A 20h retainer at €125/h. Set it once — FlowQi tracks everything from there.
Log as you work — see planned vs actual in real time
Hours land on the right project automatically. Open any engagement and instantly see: 28 of 40 hours logged, €4.200 of €6.000 used, 12 hours remaining. No spreadsheet. No math.
Invoice in one click — hours become line items
Every logged entry becomes an invoice line: date, description, hours, rate, total. Fully itemized. Clients see exactly what they're paying for — disputes become rare.
Consultants who changed how they bill
Tracking hours in a spreadsheet, invoicing 2–3 weeks late, regularly losing 8+ billable hours per month. Clients occasionally pushed back on charges because there was no detailed breakdown.
- Recovered an average of 11 billable hours per month
- Invoice disputes dropped to zero after switching to itemized billing
- Invoicing time cut from 3 hours to under 10 minutes
I used to lose at least 10 billable hours a month because I forgot to log them. Now time tracking is built into how I work and my revenue is up 20 percent — without working more hours.
[Name], Strategy Consultant · Independent
Multiple consultants each with their own tracking method. Billing coordinator spent 2 days per month consolidating hours. Client budgets often overrun without warning.
- Billing consolidation went from 2 days to 2 hours
- Budget overruns visible 2 weeks before they happen
- All client invoices now include itemized time breakdowns
My clients love the transparency. They see exactly what we worked on and when. Trust is higher, disputes are gone, and we actually get paid faster.

You're probably already using something. Here's the difference.
Most consultants track time in one tool and invoice in another — with a manual step in between. FlowQi removes that gap entirely.
| Feature | Excel & calendar | Toggl + invoicing tool | FlowQi |
|---|---|---|---|
| Time tracking | Manual, always late | Good tracking, no context | Per task, per service, per client |
| Service billing (hourly, retainer, fixed) | One model only, manual | Requires export + rebuild | All models in one place |
| Hours → invoice lines | Manual rebuild every time | Export only, manual invoice | One click — hours become line items |
| Itemized invoice breakdown | Not possible | Basic, no service context | Full breakdown per service type |
| Client & engagement management | Email and contacts only | Not included | Built in — engagement history, docs, notes |
| Budget visibility per client | Only after invoicing | Hours only, no budget link | Live — see budget vs. hours in real time |
| Retainer tracking | Manual in spreadsheet | Not supported | Monthly retainer balance auto-tracked |
| Multi-client overview | One tab per client | Projects list only | All clients, all status in one view |
| Setup time | Instant, but scales badly | Fast, but two tools to maintain | Running in under a week |

Questions consultants ask us
What is consulting software and how is FlowQi different?
Consulting software is a platform that helps advisory firms run their engagements end-to-end — from pitch and proposal through project delivery, time tracking and client invoicing. Most consulting software stops at one stage (a CRM, a time tracker, or a billing tool). FlowQi connects the whole cycle in one platform, so billable hours never leak between tools and consultants can actually see project margin in real time.
Can I handle different billing models for different clients?
Yes. FlowQi supports hourly billing, fixed-fee projects, and monthly retainers — all in the same platform. Each client can have a different model. You track hours the same way regardless, and the invoice is calculated accordingly.
How does FlowQi turn hours into invoices?
Every time entry is tagged to a client, engagement, and service type. When you're ready to invoice, FlowQi pulls all unbilled entries and generates invoice line items automatically — with a full breakdown of what was done, when, and at what rate. You review, adjust if needed, and send.
What if a client disputes a charge?
FlowQi invoices include a full itemized breakdown — date, task description, hours, and rate per line item. Clients see exactly what they're paying for. In practice, disputes become rare because there's nothing vague about what's on the invoice.
Can I manage retainer clients in FlowQi?
Yes. Set a monthly retainer budget per client. FlowQi tracks hours against the retainer in real time — so you always know how much of the retainer has been used and whether you're running over or under.
Does FlowQi work for solo consultants, or only firms?
Both. Solo consultants use FlowQi to track every hour, manage multiple clients, and invoice without admin overhead. Firms use it to consolidate time across consultants and generate consolidated client invoices.
Does FlowQi connect with my accounting software?
Yes. FlowQi integrates with Exact Online, Moneybird, QuickBooks, Xero, and AFAS. Invoice data syncs directly — so you don't enter anything twice.
