I initially had a positive experience with Tabby. After investing time upfront, my books were fully reconciled and I was caught up for the year, with only December remaining. At that point, the product appeared to be working as intended.

The issues began with how historical transaction data was handled. Tabby initially synced only approximately 90 days of bank transactions. Based on guidance in their onboarding and welcome emails, I manually uploaded the remaining months to complete the year. After reviewing, categorizing, and reconciling the full dataset, the system later re-synced extended history again, duplicating transactions.

At that point, there was no way to distinguish manually uploaded transactions from automated ones. No filters, identifiers, or deduplication tools were available to isolate or resolve the issue cleanly.

Support offered only two resolution paths:

Manually delete duplicate transactions one by one without any way to identify which entries were manual vs automated,

or

Fully reset all transactions and re-categorize everything from scratch.
Neither option meaningfully addressed the problem, as both required extensive manual effort and discarded completed work.

Over the course of roughly a month, I continued working with support. During that time, explanations shifted between 90-day bank limitations, one-time extended history pulls, deduplication logic audits, cut-off date settings, and system fixes. Despite multiple assurances that changes had been applied, the duplication issue was never resolved and historical data was not reliably restored.

Throughout the process, the burden of resolving fundamental data integrity issues was consistently placed on me through manual deletions, re-uploads, or alternative workflows, rather than the platform handling transaction history reliably.

Tabby shows promise conceptually, but in my case it failed on a core requirement: reliable transaction handling without creating additional work. The time spent correcting and troubleshooting data issues and ultimately failing to resolve the issues significantly outweighed the value provided.
