“Indinero functions as part of my company, part of my team. My peace of mind has increased tenfold around finances. I just don’t have to worry about it anymore. ”

"It's so helpful to have somebody with that level of expertise that we can just count on.We trust that you have the years of experience and now I can just ask the questions I need to, and you can help me extract the data from those numbers that I need to present to the board."
Coleen
Director of Business Operations, Lumavate
We started working together in August 2022 and since then I had only great experiences with all the team members. Jordan Burnham, Cassiopeia Coloma, Emil Natura, and Tracy Howell to name the most notable ones (in a chronological order of getting to know each person). What I value a lot in our partnership is that I am sure our accounting and taxes are done right and I can focus my attention on developing our product and taking care of our users.

“I’ve been through 10 bookkeepers in 16 years, indinero is the best we have worked with, and there is no close second. They are the first bookkeeper who successfully set us up for accrual bookkeeping. That seems a real struggle for food service companies because it is a lot of work.”

R&D Offer Quiz

Step 1 of 3

Answer to find out if you're eligible for R&D tax credits.

Do the activities performed relate to a new or improved business component’s function, performance, reliability, quality, or composition?(Required)
For Example: A mid-sized packaging company develops a slightly modified cardboard box design to improve its stacking strength (reliability) for warehouse storage, involving minor adjustments to the corrugation pattern to reduce collapse under standard weight loads.
Is your company trying to discover information to eliminate uncertainty concerning the capability or method for developing or improving a business component?(Required)
For Example: A furniture manufacturer investigates whether a cheaper wood adhesive can hold joints as effectively as the current one during assembly, testing bond strength to resolve doubts about its capability in standard production lines.
Do the activities performed constitute a process of experimentation?(Required)
For Example: An auto parts supplier runs a series of bench tests on different lubricant formulations to find one that reduces friction in engine bearings more effectively, systematically comparing wear rates over simulated operating cycles.
