My Small Business multiplayer and Collab guide: invite friends, divide printing and packing, understand Friend Boost and play together in 6-player servers.
Introduction
The Multiplayer page explains everything about playing My Small Business together: inviting friends, using the Collab feature, understanding Friend Boost and dividing up the work in 6-player shops. Servers host up to six players, and any of them can join your shop, use Collab to help print and pack, and watch the Friend Boost percentage on the HUD. Because the developer has not published exact per-friend boost numbers, this page separates what is confirmed — the 6-player cap, the Collab button and the visible boost meter — from what the community is still testing, like the precise percentage behind Friend Boost.

Core Mechanics
Multiplayer works through shared shop ownership. Up to six players can occupy one server, and friends can be invited directly to your shop. The Collab button lets other players print and pack in your shop as if it were their own production line, which speeds up shipping dramatically. While friends are active with you, the HUD shows a Friend Boost percentage that increases your earnings; the exact value per friend is not displayed. There is no evidence of VIP/private servers tied to individual shops, so co-op is designed around public servers and friend invites rather than isolated instances. Every shared action feeds the same shop state — orders, shelves, quests and the star rating all update live while the group works the line together.
Advantages
Multiplayer is a massive Coins multiplier for a simple reason: more hands on the line means faster orders. When friends divide printing from packing, you clear quests faster, ship more per minute and trigger Friend Boost on top of everything else. Collab turns your shop into a shared production floor, so even a single helper roughly doubles your throughput without extra upgrades. Six-player servers are the extreme version of this, with every player focusing on one or two tasks while the boost meter climbs. For players who have friends, running multiplayer is one of the fastest and most fun ways to out-earn solo grinding.
Challenges
Multiplayer has three real limits. Friend Boost values per friend are not published, so you cannot calculate the exact combined boost the way you can with goodie percentages — the HUD shows a number, but the formula behind it stays hidden. The 6-player cap means coordinated groups need to plan who does what, because idle helpers waste the shared shop's limited work. Finally, there is no evidence of VIP or private servers, so you cannot isolate your shop from public servers; groups have to coordinate through the standard invite and Collab tools. Because the group shares one economy, a careless teammate packing off-theme orders can drag the star rating down for everyone — communication matters as much as clicking fast.

Quick Tips
Set up a clear division of labour before the orders pile up. In a 6-player shop, assign one player to design and print, one to cut, one to pack and one to manage boxes and goodies. A shop where everyone tries to do everything produces chaos, while role-based play pushes shipping speed and quest progress much higher.
Watch the Friend Boost meter on the HUD rather than computing per-friend values. The developer has not published exact numbers, so the visible percentage is the only reliable information you have. Use it to decide when to invite more friends and when your group is already big enough. When the meter stops climbing with more friends, your current group size is likely already the practical cap.
Use Collab even with one friend. A single helper dividing tasks roughly doubles throughput: they handle printing or packing while you do the other, and every order ships faster. Boosts, quest counters and the star rating all improve when the shop runs like a real two-person line. The role split also reduces collision in the shared shop, because each station stays occupied by one player.
Deadline-coordinate event grinds with friends. During Live events like the Plushies & Craft Fair, sessions are more efficient as a group because the shared line clears orders quickly and event quests progress together. Log on at the same UTC time, divide roles and clear the event windows before they close.
