1. The central Axiom

No Jewish benefit from Shabbat in a commercial shutfus.
Siman רמ״ה codifies the structure of the shutfus Jew/non-Jew. The central mechanism: תְּנַאי מֵעִקָּרָא — to stipulate from the outset that Shabbat profits will go to the non-Jewish partner alone (with another day's profits going to the Jew as compensation). Without this initial condition, the Jew is co-owner of Shabbat profits → forbidden. On מראית עין the sources of the siman go the other way: in a genuine partnership they do not fear it, since everyone knows the non-Jew has a share in the business (מ״א ס״ק א; מ״ב ס״ק א and ס״ק י), and the Alter Rebbe permits it even בפרהסיא (שו״ע הרב סעיף י״ג). Where these sources do bring it back: when the business is recognizable and known by the Jew's name, it becomes forbidden again (מ״ב ס״ק י״ח, referring to שו״ע או״ח רמ״ג:א).

2. The 3 conditions

#ConditionWhy
1תְּנַאי מֵעִקָּרָא (initial written condition)Structures Shabbat profits outside the Jew
2No Jew in Shabbat activityAvoids direct agency
3The business is not known as the Jew's aloneIn a genuine partnership the sources of the siman do not fear מראית עין (מ״ב ס״ק י; שו״ע הרב סעיף י״ג); it returns where the business is recognizable and known by the Jew's name (מ״ב ס״ק י״ח, referring to שו״ע או״ח רמ״ג:א)

3. Hierarchy of cases

LevelTypePermitted?
1Tnai me'ikara + no Jew on Shabbat + no mar'it ayin✓
2Passive investment (stocks, funds)✓ — the Mechaber permits the Jew to give his money to the non-Jew to trade with and to share all the profit (שו״ע או״ח רמ״ה:ד); the Rama restricts it: if each works his own day and the Jew must work against what the non-Jew did on Shabbos, it is forbidden (רמ״א או״ח רמ״ה:ד). The application to stocks and funds is an extension of this seif, not a psak of the source.
3Tnai me'ikara + common storefront visible on Shabbat✓ — a genuine partnership raises no מראית עין, even בפרהסיא (שו״ע הרב סעיף י״ג; מ״ב ס״ק י)
4Without tnai me'ikaraForbidden; rectify (future only)
5Jew present in Shabbat managementAlways forbidden

4. Mnemonic — T-S-M

T — Tnaï mé'ikara (תנאי מעיקרא): initial written condition at the very creation of the shutfus.

S — Shabbat au non-juif (Shabbat to the non-Jewish partner): Shabbat profits 100% to the non-Jewish partner, counterpart on another day for the Jew.

M — Mar'it ayin: no visible Jewish signage on a business open on Shabbat.

To memorize: "T-S-M for siman 245: initial Tnai, Shabbat to the non-Jewish partner, no Mar'it ayin."

5. Decision tree

Q1: Operational shutfus or passive investment?
↓
If passive → permitted without tnai (שו״ע או״ח רמ״ה:ד), subject to the Rama's restriction on that same seif
↓
Q2: Tnai me'ikara (initial written condition)?
↓
If no → FORBIDDEN; rectify (future tnai only)
↓
Q3: Jew present in Shabbat management?
↓
If yes → ALWAYS FORBIDDEN
↓
Q4: Is the business known as the Jew's alone (his name on the sign)?
↓
If yes → forbidden (מ״ב ס״ק י״ח); if not, the partnership raises no מראית עין (שו״ע הרב סעיף י״ג)
↓
✓ Halakhically valid shutfus

6. Mehaber vs Rama

SubjectMehaberRama
Tnai me'ikaraMandatory for operational shutfusהגהה on the בדיעבד at seif א: "ויש מתירין השכר בדעבד אפילו לא התנו וחלקו סתם … ונ״ל דבהפסד גדול יש לסמוך עלייהו" (רמ״א או״ח רמ״ה:א)
מראית עין of the common storefrontThe Mehaber does not use the expression מראית עין in this siman; he gives its reason at seif ד — "וכן אין העסק ניכר ממי הוא" (שו״ע או״ח רמ״ה:ד)Nor does the Rama use it; the Acharonim do, and it is thus that they read this clause of the Mehaber — מ״א ס״ק א, מ״ב ס״ק א · י · י״ח, שו״ע הרב סעיף י״ג
Without tnai, rectifyFuture tnai onlyLenient on rectification modalities

7. 5 common pitfalls

Pitfall 1: Believing that paying the non-Jewish partner "for his Shabbat hours" is sufficient. Wrong — without an initial condition at the moment of creation, it is after-the-fact patching.
Pitfall 2: Thinking that the tnai can be verbal only. Prefer written in the shutfus contract.
Pitfall 3: Storefront with signage "Goldberg & Schmidt" open on Shabbat. Mar'it ayin — a business known by the Jew's name becomes forbidden again (מ״ב ס״ק י״ח, referring to שו״ע או״ח רמ״ג:א).
Pitfall 4: Confusing passive investment (stocks = OK) with operational shutfus (= tnai required).
Pitfall 5: Thinking that automatic e-commerce exempts from the tnai. Wrong — revenues continue to flow into the common account.

8. Modern practical cases

CaseConduct
Jewish/non-Jewish restaurantInitial tnai + no Jew on Shabbat + prefer to close or use neutral signage
E-commerce with partnerInitial tnai + zero Jewish action on Shabbat
Passive stock market investmentPermitted (not an operational shutfus)
Hotel shutfusInitial tnai + no Jew at reception on Shabbat + neutral signage
Startup with non-Jewish investorDepending on involvement: if Jewish CEO active on Shabbat = forbidden
AirBnB shutfusInitial tnai + Shabbat profits = to the non-Jewish partner
Physical store 7/7Tnai + visible non-Jewish name on Shabbat
Real estate (property management)Depending: passive (OK) or active (tnai)

10. The 5 practical golden rules

For daily conduct

  1. Initial written condition at the very creation of the shutfus
  2. Shabbat profits to the non-Jewish partner alone — counterpart on another day
  3. No Jew in Shabbat activity in the shutfus
  4. Check that the business is not known as the Jew's alone (מ״ב ס״ק י״ח) — in a genuine partnership there is no מראית עין (שו״ע הרב סעיף י״ג)
  5. Passive investment ≠ operational shutfus (separate case)
