THE WORKFLOW
A process built around the work—not a form.
You do not need to know every technical term before reaching out. The review step is there to turn incomplete information into a quote both sides can understand.
02
We review the work
Haldan looks through the actual files and follows up where dimensions, standards, materials, or intended deliverables need clarification.
Initial response within one business day
03
You receive a defined quote
The quote states what will be delivered, the price, expected schedule, payment arrangement, and what level of revision is included.
No automated estimate and no surprise scope04
Work stays organized
After approval, new information, revised source files, questions, invoices, and Haldan deliverables stay attached to the project in your portal.
A clear record instead of a scattered email chain
05
Review and receive your files
You review the agreed deliverables, request any included adjustments, and receive the final native and neutral-format files for your records.
Project history remains available through your accountTWO WAYS TO WORK

MANUAL QUOTING IS INTENTIONAL
Your files are reviewed by the person doing the work.
No algorithm guesses at scope, tolerances, cleanup time, or the condition of your source files.
