Add the Timeline
Start with the historical movement record the client already has instead of a blank spreadsheet.

Your client didn't keep a mileage log. Give Thoth the packet.
Drop in the Google Timeline export and the supporting records you actually received—1099s, platform statements, bank records, and other evidence. IbisTrace identifies the documents, preserves what each one actually reports, reconstructs supported mileage, and sends the uncertain remainder to review.
Record-reconstruction software, not legal or tax advice. Your firm remains the final reviewer.Packet in. Review tail out.Let staff review exceptions instead of rebuilding the year.

The client folder is the starting point, not a pre-sorting assignment.
IbisTrace is designed for the case where the records exist but the mileage log does not. Instead of making staff classify every document and reconstruct every trip by hand, Thoth starts with the packet and narrows the work.
Drop in the packet
Add folders or files containing 1099s, platform statements, bank records, and other supporting documents without pre-sorting them first.
Let Thoth narrow the case
Documents are identified, supported trips are resolved in batches, and possible duplicates or uncertain evidence remain visible for review.
Review the residue
Your firm reviews the facts and unresolved tail, then exports the reconstructed record when the case is ready.
Built for the client who brings everything except a clean mileage log.
No mileage log
Reconstruct past driving from historical location data and the records the client still has.
Mixed client packet
Give Thoth 1099s, platform statements, bank records, and supporting files in one intake instead of manually routing every document first.
Multi-platform work
Reconstruct the driving record across Uber, Lyft, DoorDash, Walmart Spark, Instacart, and other independent work without treating one platform as the whole story.
Proof of work
See how much manual review disappeared before the reviewer started.
In one 2,788-trip reconstruction, Thoth resolved 2,331 trips before manual review, leaving 457 trips in the unresolved queue—83.6% of the original trip-review workload removed before the reviewer began the tail.
That is an example reconstruction, not a promised result. Outcomes depend on the Timeline quality, the facts available, and the supporting evidence in the case.
Thoth reconstructs the record. Your firm decides the tax treatment.
IbisTrace keeps taxpayer-provided facts, IbisTrace-derived evidence, and tax treatment conceptually separate. Tax-document amounts are preserved according to what the form actually reports instead of being silently promoted into a generic annual-gross number.
Taxpayer facts
Client declarations remain identifiable as client-provided facts rather than machine conclusions.
IbisTrace evidence
Document classifications, trip support, and reconstruction decisions remain reviewable instead of disappearing into a black-box total.
Tax treatment
Your CPA, EA, or tax professional remains responsible for applying the law and making the final filing decision.
Already researching the reconstruction itself?
See how the underlying mileage reconstruction works.
IbisTrace's core workflow is automatic mileage reconstruction: use historical Timeline data and supporting evidence to resolve supported trips first, then concentrate human review on the remaining uncertainty.
For the broader driver-facing record problem, see the mileage log overview.
Give Thoth the case your staff does not want to rebuild by hand.
Start with the Timeline and the client packet you already have. Let IbisTrace show you what still requires a human.
