StoFlow vs You-Sync: publishing or tracking your Vinted sales

You-Sync and StoFlow address two different main needs: You-Sync tracks your sales, margins and DAC7 thresholds from your Vinted emails, without ever publishing; StoFlow publishes your listings and removes a sold piece from the other marketplaces. Comparing the two therefore means choosing which need you want to cover, or using both.

The facts about You-Sync come from its official pages, accessed on 06 Oct 2026. What these pages do not say is not written here.

What does You-Sync do according to its official page?

You-Sync presents itself as a management tool for Vinted sellers (source: you-sync.fr/cgu, article 2, accessed 06 Oct 2026). Its FAQ explains that there is "no bot, no extension, no automation on Vinted" (source: you-sync.fr/faq, accessed 06 Oct 2026). It works by forwarding your Vinted sale emails through a Gmail filter; for now, only Gmail is indicated as compatible.

According to its pages (source: you-sync.fr, accessed 06 Oct 2026):

• Sales and margin tracking, linked to items through a code placed in the listing title (source: you-sync.fr/faq, accessed 06 Oct 2026);
• DAC7 threshold and URSSAF provision tracking, without filing the declaration on your behalf (source: you-sync.fr/faq, accessed 06 Oct 2026);
• Automatic pro invoicing in the Pro offer;
• Excel and CSV exports in the Pro offer.

It also states that it will never republish on your behalf and will never touch your account. The free plan tracks up to 20 sales per month, with no bank card and no time limit (source: you-sync.fr/faq, accessed 06 Oct 2026). The paid offers are displayed at 12.90 euros per month (unlimited sales) and 24.90 euros per month (Pro offer), with no commitment; the home page gives neither an annual price nor an excl. or incl. VAT mention, but the terms of sale state that the company benefits from the VAT franchise (article 293 B of the French tax code), so these prices carry no VAT (source: you-sync.fr and you-sync.fr/cgu, article 4, accessed 06 Oct 2026).

Which need does each tool cover?

Each tool covers a part of tracking: You-Sync focuses on tax (DAC7 thresholds, URSSAF provision), while StoFlow offers an Accounting section from the Pro plan (sales, expenses, Excel and FEC exports). You-Sync reads emails to follow activity after the sale; it does not connect to your Vinted account. StoFlow acts before the sale: it publishes listings (automatic republishing from the Pro plan), connects several marketplaces and removes a sold piece from the other marketplaces. StoFlow does not automatically invoice your buyers as of 06 Oct 2026.

On marketplaces, You-Sync's page names only Vinted (source: you-sync.fr, accessed 06 Oct 2026). StoFlow covers Vinted and Leboncoin from the Free plan (up to 100 products), eBay France on Starter, Vestiaire Collective and Opla (in beta) on Pro, then Etsy and eBay across 9 countries on Business.

Read this table with the following caveat: a "No" or "Not documented" entry for You-Sync does not indicate a shortcoming; You-Sync presents itself as a management tool for Vinted.

Where You-Sync is better

• Tax tracking at the heart of the offer. You-Sync's tax assistant tracks DAC7 thresholds and the URSSAF provision, and its DAC7 gauges are included from the free plan (source: you-sync.fr, accessed 06 Oct 2026). StoFlow offers, from the Pro plan, an Accounting section with Excel and FEC exports.
• No action on your Vinted account. It publishes nothing and does not connect to your account, which suits someone who wants tracking without automation (source: you-sync.fr/faq, accessed 06 Oct 2026).
• A free plan with no time limit to track up to 20 sales per month, and a paid offer with no commitment (source: you-sync.fr/faq, accessed 06 Oct 2026). The pages read do not specify whether these 20 sales are counted per calendar month or over a rolling period.

Which seller should choose You-Sync, and which should choose StoFlow?

You-Sync suits you if your main need is knowing where you stand: margins, DAC7 thresholds, URSSAF provision, without touching your listings. For the tax context, our guide Vinted tax 2026 sets out the basics.

StoFlow suits you if your need is saving time on publishing: create a product page once, publish it on Vinted and Leboncoin, and remove the listing from the other marketplaces when the piece sells, according to your confirmation setting (see the article on stock synchronisation). The Starter plan costs 14.99 euros per month, and the free plan is enough to start.

Both are possible: one handles the selling, the other the tracking. Neither the home page, the FAQ nor the terms of You-Sync (accessed 06 Oct 2026) forbid using another tool in parallel; check that this setup suits you.

How can you test before choosing?

Start with the most pressing need. If it is tracking, try You-Sync's free plan on your first 20 sales of the month (source: you-sync.fr/faq, accessed 06 Oct 2026). If it is publishing, connect Vinted and Leboncoin on StoFlow's free plan and publish a test batch. To place StoFlow among publishing tools, see best crosslisting software 2026.

These facts are dated 06 Oct 2026: re-read the official pages before subscribing. If you are unsure, ask yourself a simple question: does most of your time go into publishing listings, or into tracking what you have already sold? The answer tells you which tool to try first, and nothing stops you from adding the other one later, once your sales volume has stabilised.
